Open-File Report OF 01-311 contains a digital geologic map database of the Cucamonga Peak 7.5’ quadrangle, San Bernardino County, California that includes:
\n1. ARC/INFO (Environmental Systems Research Institute, http://www.esri.com) version 7.2.1 coverages of the various elements of the geologic map
\n2. A PostScript file to plot the geologic map on a topographic base, and containing a Correlation of Map Units diagram, a Description of Map Units, an index map, and a regional structure map
\n3. Portable Document Format (.pdf) files of:
\na. This Readme; includes in Appendix I, data contained in fif_met.txt
\n\nb. The same graphic as plotted in 2 above. (Test plots have not produced 1:24,000-scale map sheets. Adobe Acrobat pagesize setting influences map scale.)
The Correlation of Map Units and Description of Map Units is in the editorial format of USGS Miscellaneous Investigations Series (I-series) maps but has not been edited to comply with I-map standards. Within the geologic map data package, map units are identified by standard geologic map criteria such as formation-name, age, and lithology. Even though this is an author-prepared report, every attempt has been made to closely adhere to the stratigraphic nomenclature of the U. S. Geological Survey. Descriptions of units can be obtained by viewing or plotting the .pdf file (3b above) or plotting the postscript file (2 above). If roads in some areas, especially forest roads that parallel topographic contours, do not show well on plots of the geologic map, we recommend use of the USGS Cucamonga Peak 7.5’ topographic quadrangle in conjunction with the geologic map.

It includes the western flank of Frazier Mountain, southern Lockwood Valley, and a region of the Los Padres National Forest near northern Piru Creek.\r\n\r\n The oldest rocks are mostly biotite augen gneiss, in the hanging wall of the Frazier Mountain thrust and in a large body south of the thrust. A U-Pb zircon age for the gneiss is 1690+5 Ma (W. Premo, unpublished data). Two Cretaceous intrusive rocks are named the quartz monzonite of Sheep Creek and the coarse-grained granodiorite of Lockwood Peak. A U-Pb zircon age on the latter is 76.05+0.22 Ma (W. Premo, unpublished data).\r\n\r\n The northeastern edge of a large Eocene marine basin, comprising the sandstones, shales, and conglomerates of the Juncal Formation, occupies the southwestern 25 percent of the quadrangle. Miocene fluvial rocks, including coarse boulder conglomerates, sandstones, and shale, of the Caliente Formation crop out mostly in the northwestern part of the quadrangle. Commercially exploitable Lockwood Clay unconformably overlies the Caliente, which, in turn, is overlain by the mostly fluvial Pliocene Quatal Formation.\r\n\r\n Two major south-directed thrusts, the Frazier Mountain thrust and the South Frazier Mountain thrust, place crystalline rocks over Miocene and Pliocene sedimentary rocks. The South Frazier Mountain thrust is transected by the newly recognized, north-directed Lockwood Peak reverse fault. In addition, the newly recognized south-directed Yellowjacket thrust displaces rocks of the Pliocene Quatal Formation.","language":"ENGLISH","doi":"10.3133/ofr99130","usgsCitation":"Kellogg, K., 2001, Geologic map of the Lockwood Valley Quadrangle, Ventura County, California (Version 1.0): U.S. Geological Survey Open-File Report 99-130, 8 p., 1 over-size sheet., https://doi.org/10.3133/ofr99130.","productDescription":"8 p., 1 over-size sheet.","costCenters":[],"links":[{"id":110151,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_34849.htm","linkFileType":{"id":5,"text":"html"},"description":"34849"},{"id":160931,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3021,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/ofr-99-0130/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afbe4b07f02db6963a8","contributors":{"authors":[{"text":"Kellogg, Karl S.","contributorId":89896,"corporation":false,"usgs":true,"family":"Kellogg","given":"Karl S.","affiliations":[],"preferred":false,"id":205769,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":31363,"text":"ofr200155 - 2001 - Evaluation of the location and recency of faulting near prospective surface facilities in Midway Valley, Nye County, Nevada","interactions":[],"lastModifiedDate":"2022-07-01T19:59:25.772334","indexId":"ofr200155","displayToPublicDate":"2002-01-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-55","title":"Evaluation of the location and recency of faulting near prospective surface facilities in Midway Valley, Nye County, Nevada","docAbstract":"Evaluation of surface faulting that may pose a hazard to prospective surface facilities is an important element of the tectonic studies for the potential Yucca Mountain high-level radioactive waste repository in southwestern Nevada. For this purpose, a program of detailed geologic mapping and trenching was done to obtain surface and near-surface geologic data that are essential for determining the location and recency of faults at a prospective surface-facilities site located east of Exile Hill in Midway Valley, near the eastern base of Yucca Mountain. The dominant tectonic features in the Midway Valley area are the north- to northeast-trending, west-dipping normal faults that bound the Midway Valley structural block-the Bow Ridge fault on the west side of Exile Hill and the Paint-brush Canyon fault on the east side of the valley. Trenching of Quaternary sediments has exposed evidence of displacements, which demonstrate that these block-bounding faults repeatedly ruptured the surface during the middle to late Quaternary. Geologic mapping, subsurface borehole and geophysical data, and the results of trenching activities indicate the presence of north- to northeast-trending faults and northwest-trending faults in Tertiary volcanic rocks beneath alluvial and colluvial sediments near the prospective surface-facilities site. North to northeast-trending faults include the Exile Hill fault along the eastern base of Exile Hill and faults to the east beneath the surficial deposits of Midway Valley. These faults have no geomorphic expression, but two north- to northeast-trending zones of fractures exposed in excavated profiles of middle to late Pleistocene deposits at the prospective surface-facilities site appear to be associated with these faults. Northwest-trending faults include the West Portal and East Portal faults, but no disruption of Quaternary deposits by these faults is evident. The western zone of fractures is associated with the Exile Hill fault. The eastern zone of fractures is within Quaternary alluvial sediments, but no bedrock was encountered in trenches and soil pits in this part of the prospective surface facilities site; thus, the direct association of this zone with one or more bedrock faults is uncertain. No displacement of lithologic contacts and soil horizons could be detected in the fractured Quaternary deposits. The results of these investigations imply the absence of any appreciable late Quaternary faulting activity at the prospective surface-facilities site.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr200155","collaboration":"Prepared in cooperation with the Nevada Operations Office, U.S. Department of Energy","usgsCitation":"Swan, F., Wesling, J., Angell, M.M., Thomas, A.P., Whitney, J., and Gibson, J.D., 2001, Evaluation of the location and recency of faulting near prospective surface facilities in Midway Valley, Nye County, Nevada (Version 1.0.): U.S. Geological Survey Open-File Report 2001-55, vi, 66 p., https://doi.org/10.3133/ofr200155.","productDescription":"vi, 66 p.","costCenters":[{"id":226,"text":"Earth Science Investigations Program","active":false,"usgs":true}],"links":[{"id":160965,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":9824,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://www.osti.gov/bridge/servlets/purl/771112-GgLvJI/native/771112.PDF","linkFileType":{"id":1,"text":"pdf"}},{"id":9822,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://www.osti.gov/bridge/product.biblio.jsp?osti_id=771112","linkFileType":{"id":5,"text":"html"}},{"id":402880,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_46523.htm"}],"country":"United States","state":"Nevada","county":"Nye County","otherGeospatial":"Midway Valley","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -116.4389,\n 36.8431\n ],\n [\n -116.4208,\n 36.8431\n ],\n [\n -116.4208,\n 36.8611\n ],\n [\n -116.4389,\n 36.8611\n ],\n [\n -116.4389,\n 36.8431\n ]\n ]\n ]\n }\n }\n ]\n}","edition":"Version 1.0.","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a08e4b07f02db5fa5ac","contributors":{"authors":[{"text":"Swan, F.

The array is operated by the Geologic Hazards Team of the U. S Geological Survey. It has been recording small local earthquakes since its initial installation immediately after the Duvall earthquake in May 1996. Since then, we have been able to convert the array to all Kinemetrics K2s after retiring the aging DR-200s in June of 1998. The array stations have been moved around to suit our research interests. We had 26 instruments in urban Seattle at the time of the Nisqually earthquake.
\nThe primary research goal of the array is to record earthquake ground motion at sites scattered around the city that represent the major types of surficial geologic materials found in the city. With this information we plan to draw seismic hazard maps that will show the expected variability of ground shaking throughout the city. Our strategy to achieve our goal includes:
\n1) sampling ground motion at sites that represent the major geologic materials including man-made fill and alluvial surficial materials,
\n2) recording high-resolution ground motions from a tripartite array (SDN, SDS, and SDW) with about 200 meter spacing located on man-made fill in the SoDo (South of Downtown) industrial district,
\n3) recording ground motion in areas with man-made fill and alluvial surficial materials which have a high potential for liquifaction,
\n4) sampling ground motion at two sites on Capitol Hill (THO, and SEU) that are located near drill holes that have been logged for seismic velocity,
\n5) Providing long-term continuity at a few sites for comparison and reference, especially SEW and ALK, which are located on Tertiary bedrock.
\n6) recording ground motion at sites with similar surficial geology both inside and outside the Seattle Basin

The study is intended to provide land-use planners and managers, particularly in the Bureau of Land Management, with a foundation of knowledge that will allow them to anticipate and plan for demand for and development of sand and gravel resources on public lands in response to the urban growth. Attributes under study include: regional geology of both alluvial source areas as well as deposits; fluvial processes that led to deposition of the sand and gravel deposits; spatial distribution of the deposits; quantity and quality of materials in the deposits; and the suitability of the deposits for a range of applications. The study will also examine and attempt to model the association between fluvial processes, deposit characteristics, and physical specifications for various applications of sand and gravel. The results will be presented in a series of sand and gravel assessment reports of which this is the first.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01130","usgsCitation":"Bliss, J.D., and Moyle, P.R., 2001, Assessment of the sand and gravel resources of the Lower Boise River Valley area, Idaho: Part one: Geological framework of the sand and gravel deposits: U.S. Geological Survey Open-File Report 2001-130, Report: 41 p., Readme, https://doi.org/10.3133/ofr01130.","productDescription":"Report: 41 p., Readme","numberOfPages":"41","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":160836,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr01130.jpg"},{"id":282078,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0130/pdf/of01-130.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":3028,"rank":4,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0130/","linkFileType":{"id":5,"text":"html"}},{"id":282079,"rank":2,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/2001/0130/readme.doc"},{"id":410562,"rank":5,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_43368.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Idaho","otherGeospatial":"Boise River","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -117,\n 43.417\n ],\n [\n -117,\n 43.917\n ],\n [\n -116,\n 43.917\n ],\n [\n -116,\n 43.417\n ],\n [\n -117,\n 43.417\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abae4b07f02db671cff","contributors":{"authors":[{"text":"Bliss, James D. jbliss@usgs.gov","contributorId":2790,"corporation":false,"usgs":true,"family":"Bliss","given":"James","email":"jbliss@usgs.gov","middleInitial":"D.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":205798,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moyle, Phillip R.","contributorId":100898,"corporation":false,"usgs":true,"family":"Moyle","given":"Phillip","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":205799,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":31413,"text":"ofr01333 - 2001 - A procedural manual for measurement of uranium and thorium isotopes utilizing the USGS-Stanford Finnegan Mat 262","interactions":[],"lastModifiedDate":"2014-02-25T13:50:22","indexId":"ofr01333","displayToPublicDate":"2002-01-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-333","title":"A procedural manual for measurement of uranium and thorium isotopes utilizing the USGS-Stanford Finnegan Mat 262","docAbstract":"Over the past several decades investigators have extensively examined the 238U-234U- 230Th systematics of a variety of geologic materials using alpha spectroscopy. Analytical uncertainty for 230Th by alpha spectroscopy has been limited to about 2% (2σ). The advantage of thermal ionization mass spectroscopy (TIMS), introduced by Edwards and co-workers in the late 1980’s is the increased detectability of these isotopes by a factor of ~200, and decreases in the uncertainty for 230Th to about 5‰ (2σ) error.
\nThis report is a procedural manual for using the USGS-Stanford Finnegan-Mat 262 TIMS to collect and isolate Uranium and Thorium isotopic ratio data. Chemical separation of Uranium and Thorium from the sample media is accomplished using acid dissolution and then processed using anion exchange resins.
\nThe Finnegan-Mat262 Thermal Ionization Mass Spectrometer (TIMS) utilizes a surface ionization technique in which nitrates of Uranium and Thorium are placed on a source filament. Upon heating, positive ion emission occurs. The ions are then accelerated and focused into a beam which passes through a curved magnetic field dispersing the ions by mass. Faraday cups and/or an ion counter capture the ions and allow for quantitative analysis of the various isotopes.

Conceptually, the structural framework of the Silent Canyon caldera is based on the idea of collapse of the caldera roof over a shallow magma chamber to form a structural basin following violent volcanic eruptions. Calderas are common in certain volcanic regions of the world, and most well-exposed calderas are broadly similar to each other, particularly the arcuate or circular shape of their collapse depression. There are other reasons for modeling the Silent Canyon caldera as a circular feature in addition to knowledge that calderas throughout the world are generally circular features. The Silent Canyon caldera is the site of one of the largest gravity lows in the Western United States, indicating a thick accumulation of low-density rocks such as lavas and tuffs—a fact confirmed by drilling on Pahute Mesa. This gravity low is bowl-shaped, and the uppermost volcanic units on Pahute Mesa form a circular outcrop pattern of inward-dipping tuff interpreted to be the result of their filling the upper part of the bowl-shaped depression. Together, these features are consistent with, and indicative of, a circular collapse structural model for the Silent Canyon caldera. The collapse depression of the Silent Canyon caldera, bounded by arcuate faults, is filled with as much as 6 km (19,800 ft) of volcanic and sedimentary rocks that are considerably less dense than the underlying and surrounding basement rocks. The boundary surface between less dense caldera fill and more dense basement is modeled as the caldera ring fault.

Identifying sources of metals from various\r\ndrainage areas was determined using a tracer injection approach\r\nand synoptic sampling during low flow conditions on September\r\n29, 1999 to determine loads. The tracer data was interpreted\r\nin conjunction with detailed geologic mapping, topographic profiling,\r\ngeochemical characterization, and the occurrence and\r\ndistribution of trace metals to identify sources of ground-water\r\ninflows. For this highly mineralized sub-basin, we demonstrate\r\nthat SO4, Al, and Fe load contributions from drainage areas that\r\nhave experienced historical mining?although substantial?are\r\nrelatively insignificant in comparison with SO4, Al, and Fe\r\nloads from areas experiencing natural weathering of highlyaltered,\r\npyritic rocks.\r\nRegional weathering of acid-sulfate mineral assemblages\r\nproduces moderately low pH waters elevated in SO4, Al, and\r\nFe; but generally lacking in Cu, Cd, Ni, and Pb. Samples\r\nimpacted by mining are also characterized by low pH and large\r\nconcentrations of SO4, Al, and Fe; but contained elevated dissolved\r\nmetals from ore-bearing vein minerals such as Cu, Zn,\r\nCd, Ni, and Pb. Occurrences of dissolved trace metals were\r\nhelpful in identifying ground-water sources and flow paths. For\r\nexample, cadmium was greatest in inflows associated with\r\ndrainage from inactive mine sites and absent in inflows that\r\nwere unaffected by past mining activities and thus served as an\r\nimportant indicator of mining contamination for this environmental\r\nsetting.\r\nThe most heavily mine-impacted reach (PG153 to PG800),\r\ncontributed 8% of the discharge, and 11%, 9%, and 12% of the\r\ntotal SO4, Al, and Fe loads in Prospect Gulch. The same reach\r\nyielded 59% and 37% of the total Cu and Zn loads for the subbasin.\r\nIn contrast, the naturally acidic inflows from the Red\r\nChemotroph iron spring yielded 39% of the discharge and 54%,\r\n73%, and 87% of the SO4, Al, and Fe loads; but only 4% of the\r\ntotal Cu and 30% of the total Zn loads in Prospect Gulch.\r\nBase flow from the Prospect Gulch sub-basin contributes\r\nabout 4.8 percent of the total discharge at the mouth of Cement\r\nCreek; compared with sampled instream loads of 1.8%, 8.8%,\r\n15.9%, 28%, and 8.6% for SO4, Al, Fe, Cu and Zn, respectively.\r\nWater-shed scale remediation efforts targeted at reducing loads\r\nof SO4, Al, and Fe at inactive mine sites are likely to fail\r\nbecause the major sources of these constituents in Prospect\r\nGulch are predominantly discharged from natural sources.\r\nRemediation goals aimed at reducing acidity and loads of Cu\r\nand other base metals, may succeed, however, because changes\r\nin pH and loads are disproportionately greater than increases in\r\ndischarge over the same reach, and a substantial fraction of the\r\nmetal loading is from mining-impacted reaches. Whether remediation\r\nof abandoned mines in Prospect Gulch can be successful\r\ndepends on how goals are defined?that is, whether the objective\r\nis to reduce loads of SO4, Al, and Fe; or whether loads of\r\nCu and other base metals and pH are targeted.","language":"ENGLISH","doi":"10.3133/ofr01258","usgsCitation":"Wirt, L., Leib, K.J., Melick, R., and Bove, D.J., 2001, Metal loading assessment of a small mountainous sub-basin characterized by acid drainage -- Prospect Gulch, upper Animas River watershed, Colorado (Version 1.1): U.S. Geological Survey Open-File Report 2001-258, 36 p., https://doi.org/10.3133/ofr01258.","productDescription":"36 p.","costCenters":[],"links":[{"id":160567,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":2516,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/ofr-01-0258/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48afe4b07f02db52f212","contributors":{"authors":[{"text":"Wirt, Laurie","contributorId":13204,"corporation":false,"usgs":true,"family":"Wirt","given":"Laurie","affiliations":[],"preferred":false,"id":205880,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Leib, Kenneth J. 0000-0002-0373-0768 kjleib@usgs.gov","orcid":"https://orcid.org/0000-0002-0373-0768","contributorId":701,"corporation":false,"usgs":true,"family":"Leib","given":"Kenneth","email":"kjleib@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":205878,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Melick, Roger","contributorId":100033,"corporation":false,"usgs":true,"family":"Melick","given":"Roger","affiliations":[],"preferred":false,"id":205881,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bove, Dana J. dbove@usgs.gov","contributorId":4855,"corporation":false,"usgs":true,"family":"Bove","given":"Dana","email":"dbove@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":205879,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":31394,"text":"ofr01237 - 2001 - Eagle Mountain Mine: Geology of the former Kaiser Steel Operation in Riverside County, California","interactions":[],"lastModifiedDate":"2023-06-26T18:25:24.100894","indexId":"ofr01237","displayToPublicDate":"2002-01-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-237","title":"Eagle Mountain Mine: Geology of the former Kaiser Steel Operation in Riverside County, California","docAbstract":"This investigation of the Eagle Mountain Mine area, though cursory, revealed new structural, alteration, and stratigraphic relations. Eagle Mountain ores were previously an important source of iron to the western U. S. Ore (where fresh) is magnetite-pyrite rock forming two stratabound horizons virtually continuous for 11 km.\n\nGneissic basement rocks are overlain by two sedimentary units, separated by unconformities. The lower unit contains carbonate rocks and quartzite; the \"vitreous quartzite\" of previous workers, however, is an alteration feature rather than a stratigraphic one. The upper unit contains thick conglomerates. This layered sequence of rocks is deformed into a west-plunging anticline. Intrusion by Jurassic quartz monzonite apparently followed this deformation.\n\nQuartz monzonite forms a branching network of sills, some of which dilate the contact between the upper and lower sedimentary sequences. Intrusion resulted in extensive, mostly-anhydrous skarns, but stratabound iron ore is just as closely related to some other features:\n\nregional alteration of quartz monzonite, with iron ore adjacent to little-altered rocks along the boundary between sodic and potassic domains,\nthe two unconformities, which apparently formed stratigraphic traps for precipitation of stratabound iron ores,\na north-facing monoclinal plane between folds, which was preferentially replaced.\nIron ore replaces a variety of host rocks along the two unconformities, forming massive to globular bodies, and its mineralogy correlates with deuteric alteration features, not anhydrous skarn. Its pyrite contains as much as 3% cobalt.\n\nIron was only one of five elements that showed mobility in this region on a scale that suggests basic crustal processes. The others in probable order of flux magnitude are silica, magnesium, sodium, and potassium, to form regionally distributed “vitreous quartzite”, dolomite, and secondary feldspars, respectively.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr01237","usgsCitation":"Force, E.R., 2001, Eagle Mountain Mine: Geology of the former Kaiser Steel Operation in Riverside County, California: U.S. Geological Survey Open-File Report 2001-237, 16 p., https://doi.org/10.3133/ofr01237.","productDescription":"16 p.","numberOfPages":"17","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":160664,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":282626,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0237/pdf/of01-237.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":406870,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_43367.htm","linkFileType":{"id":5,"text":"html"}},{"id":2513,"rank":5,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0237/","linkFileType":{"id":5,"text":"html"}},{"id":282627,"rank":3,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/2001/0237/readme.doc"}],"country":"United States","state":"California","county":"Riverside County","otherGeospatial":"Eagle Mountain Mine","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -115.55282592773438,\n 33.81794822741499\n ],\n [\n -115.43472290039062,\n 33.81794822741499\n ],\n [\n -115.43472290039062,\n 33.910314751382735\n ],\n [\n -115.55282592773438,\n 33.910314751382735\n ],\n [\n -115.55282592773438,\n 33.81794822741499\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a54e4b07f02db62c2bf","contributors":{"authors":[{"text":"Force, Eric R.","contributorId":32916,"corporation":false,"usgs":true,"family":"Force","given":"Eric","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":205874,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":31393,"text":"ofr01231 -

In addition to landslides, heavy rainfall caused flooding and massive debris flows that damaged coastal communities in the State of Vargas along the Caribbean Sea. Examination of the rainfall pattern obtained from the GOES-8 satellite showed that the pattern of damage was generally consistent with the area of heaviest rainfall. Field observations of the severely affected drainage basins and historical records indicate that previous flooding and massive debris-flow events of similar magnitude to that of December 1999 have occurred throughout this region.

Some 11 debris flow events that were destructive to property have been recorded between 1955 and 1998. On July 11 and 13, 1999, debris flows again occurred, produced by high-intensity, short-duration monsoon rains. Unlike previous debris flow events, the July 11 rainfall generated a high-velocity debris avalanche in Snow Creek, one of the several creeks crossing the composite, debris flow dominated, alluvial fan on which Forest Falls is located. This debris avalanche overshot the bank of the active debris flow channel of Snow Creek, destroying property in the near vicinity and taking a life. The minimum velocity of this avalanche is calculated to have been in the range of 40 to 55 miles per hour. Impact from high-velocity boulders removed trees where the avalanche overshot the channel bank. Further down the fan, the rapidly moving debris fragmented the outer parts of the upslope side of large pine trees and embedded rock fragments into the tree trunks. Unlike the characteristic deposits formed by debris flows, the avalanche spread out down-slope and left no deposit suggestive of a debris avalanche. This summer monsoon-generated debris avalanche is apparently the first recorded for Forest Falls. The best indications of past debris avalanches may be the degree of permanent scars produced by extensive abrasion and splintering of the outer parts of pine trees that were in the path of an avalanche.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr01146","usgsCitation":"Morton, D.M., and Hauser, R.M., 2001, A debris avalanche at Forest Falls, San Bernardino County, California, July 11, 1999: U.S. Geological Survey Open-File Report 2001-146, Readme TXT;

Within the geologic map data package, map units are identified by standard geologic map criteria such as formation name, age, and lithology. Even though this is an author-prepared report, every attempt has been made to closely adhere to the stratigraphic nomenclature of the U. S. Geological Survey. Descriptions of units can be obtained by viewing or plotting the .pdf file (3b above) or plotting the postscript file (2 above).

The map was produced digitally by classifying geologic-map units according to composition, mineralogy, and texture; rather than by age and stratigraphic relationships as shown on traditional geologic maps. This map differs from most lithologic maps in that the lithogeochemical unit classification distinguishes those rock units having key water-reactive minerals that may induce acid neutralization, or reduction, of hosted water at the weathering interface. The validity of these rock units, however, is independent of water chemistry, because the rock units are derived from geologic maps and rock descriptions. Areas of high soil carbon content, and sulfide metal deposits are also shown. \r\nWater-reactive minerals and their weathering reactions yield five lithogeochemical unit classes: 1) carbonate rock and calcareous rocks and sediments, the most acid-neutralizing; 2)carbonaceous-sulfidic rocks and sediments, oxygen-depleting and reducing; 3) quartzofeldspathic rocks and siliciclastic sediments, relatively weakly reactive with water; 4) mafic silicate rocks/sediments, oxygen consuming and high solute-load delivering; and, 5) the rarer calcareous-sulfidic (carbonaceous) rocks, neutralizing and reducing. Earlier studies in some parts of the map area have related solute loads in ground and stream waters to some aspects of bedrock lithology. More recent preliminary tests of relationships between four of the classes of mapped lithogeochemical units and ground water chemistry, in the Mid-Atlantic area using this map, have focused on and verified the nitrate-reducing and acid-neutralizing properties of some bedrock and unconsolidated aquifer rock types. Sulfide mineral deposits and their mine-tailings effects on waters are beginning to be studied by others. Additional testing of relationships among the lithogeochemical units and aspects of ground and surface water chemistry could help to refine the lithogeochemical classification, and this map. The testing could also improve the usefulness of the map for assessing aquifer reactivity and the transport properties of reactive contaminants such as acid rain, and nitrate from agricultural sources, in the Chesapeake Bay watershed.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01187","usgsCitation":"Peper, J.D., McCartan, L., Horton, J., and Reddy, J.E., 2001, Preliminary lithogeochemical map showing near-surface rock types in the Chesapeake Bay watershed, Virginia and Maryland: U.S. Geological Survey Open-File Report 2001-187, Report: 26 p.; 1 Plate: 48.00 × 32.00 inches; Read Me; Data Downloads, https://doi.org/10.3133/ofr01187.","productDescription":"Report: 26 p.; 1 Plate: 48.00 × 32.00 inches; Read Me; Data Downloads","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"links":[{"id":164192,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":110231,"rank":700,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_45594.htm","linkFileType":{"id":5,"text":"html"},"description":"45594"},{"id":3057,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/openfile/of01-187/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Maryland, Virginia","otherGeospatial":"Chesapeake Bay watershed","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -79.595947265625,\n 36.38591277287651\n ],\n [\n -75.76171875,\n 36.38591277287651\n ],\n [\n -75.76171875,\n 39.740986355883564\n ],\n [\n -79.595947265625,\n 39.740986355883564\n ],\n [\n -79.595947265625,\n 36.38591277287651\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abde4b07f02db6742d8","contributors":{"authors":[{"text":"Peper, John D.","contributorId":105320,"corporation":false,"usgs":true,"family":"Peper","given":"John","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":205838,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McCartan, Lucy","contributorId":20801,"corporation":false,"usgs":true,"family":"McCartan","given":"Lucy","email":"","affiliations":[],"preferred":false,"id":205837,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Horton, J.
