Except for six points, all areas of the chondrules that were analyzed had δ<sup>41</sup>K compositions that were normal within error (typically ±3%, 2s̀). The six “anomalous” points are probably all artifacts. Experiments have shown that free evaporation of K leads to large <sup>41</sup>K enrichments in the evaporation residues, consistent with Rayleigh fractionation. Under Rayleigh conditions, a 3% enrichment in δ<sup>41</sup>K is produced by ∼12% loss of K. The range of L-chondrite-normalized K/Al ratios (a measure of the K-elemental fractionation) in the areas analyzed vary by almost three orders of magnitude. If all chondrules started out with L-chondrite-like K abundances and the K loss occurred via Rayleigh fractionation, the most K-depleted chondrules would have had compositions of up to δ<sup>41</sup>K ≅ 200%. Clearly, K fractionation did not occur by evaporation under Rayleigh conditions. Yet experiments and modeling indicate that K should have been lost during chondrule formation under currently accepted formation conditions (peak temperature, cooling rate, etc.). Invoking precursors with variable alkali abundances to produce the range of K/Al fractionation in chondrules does not explain the K-isotopic data because any K that was present should still have experienced sufficient loss during melting for there to have been a measurable isotopic fractionation. If K loss and isotopic fractionation was inevitable during chondrule formation, the absence of K-isotopic fractionation in Bishunpur chondrules requires that they exchanged K with an isotopically normal reservoir during or after formation. There is evidence for alkali exchange between chondrules and rim-matrix in all unequilibrated ordinary chondrites. However, melt inclusions can have alkali abundances that are much lower than the mesostases of the host chondrules, which suggests that they at least remained closed since formation. If it is correct that some or all melt inclusions remained closed since formation, the absence of K-isotopic fractionation in them requires that the K-isotopic exchange took place during chondrule formation, which would probably require gas-chondrule exchange. Potassium evaporated from fine-grained dust and chondrules during chondrule formation may have produced sufficient K-vapor pressure for gas-chondrule isotopic exchange to be complete on the timescales of chondrule formation. Alternatively, our understanding of chondrule formation conditions based on synthesis experiments needs some reevaluation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Meteoritics and Planetary Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley-Blackwell","publisherLocation":"Hoboken, NJ","doi":"10.1111/j.1945-5100.2000.tb01469.x","usgsCitation":"Alexander, C.M., Grossman, J.N., Wang, J., Zanda, B., Bourot-Denise, M., and Hewins, R., 2000, The lack of potassium-isotopic fractionation in Bishunpur chondrules: Meteoritics and Planetary Science, v. 35, no. 4, p. 859-868, https://doi.org/10.1111/j.1945-5100.2000.tb01469.x.","productDescription":"10 p.","startPage":"859","endPage":"868","numberOfPages":"10","costCenters":[{"id":410,"text":"National Center","active":false,"usgs":true}],"links":[{"id":280829,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280828,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1945-5100.2000.tb01469.x"}],"volume":"35","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-02-04","publicationStatus":"PW","scienceBaseUri":"53cd7829e4b0b2908510bf50","contributors":{"authors":[{"text":"Alexander, C.

The data collected were used in: (a) estimating the cross-flow among the screened intervals under ambient conditions; (b) estimating the relative transmissivity adjacent to the individual screen zones; and (c) determination of the hydraulic heads at the far boundaries of the large-scale aquifer zones. These inferences were cross-checked against known hydrogeology of the aquifer-aquitard system in the study area, and the calibration results of numerical flow modeling. The major conclusions derived from the flow measurements were: (a) the presence of natural downward cross-flow under ambient condition supported the hypothesis that the upper part of the Kuwait Group aquifer in the study area was divided into a series of permeable units (aquifers), separated by confining or semi-confining beds (aquitards); (b) the head differences between the different screened zones, derived through modeling of the flowmeter data of the wells, provided additional confirmation for the division of the upper part of the Kuwait Group aquifer into compartments in the study area; (c) flowmeter data indicated that the second and third aquifers were contributing most of the water to the well bores, compared with the uppermost (first) and the lowermost (fourth) aquifers; and (d) inflow to the wells during pumping was associated with discrete sub-intervals in the screened zones, controlled by local aquifer heterogeneity, and possibly clogging of screens and gravel pack.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/S0022-1694(00)00261-4","usgsCitation":"Paillet, F.L., Senay, Y., Mukhopadhyay, A., and Szekely, F., 2000, Flowmetering of drainage wells in Kuwait City, Kuwait: Journal of Hydrology, v. 234, no. 3-4, p. 208-227, https://doi.org/10.1016/S0022-1694(00)00261-4.","productDescription":"20 p.","startPage":"208","endPage":"227","numberOfPages":"20","costCenters":[],"links":[{"id":282094,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282093,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0022-1694(00)00261-4"}],"country":"Kuwait","city":"Kuwait City","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 46.5565,28.5138 ], [ 46.5565,30.1038 ], [ 48.6723,30.1038 ], [ 48.6723,28.5138 ], [ 46.5565,28.5138 ] ] ] } } ] }","volume":"234","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5a00e4b0b290850f90d0","contributors":{"authors":[{"text":"Paillet, Frederick L.","contributorId":63820,"corporation":false,"usgs":true,"family":"Paillet","given":"Frederick","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":490028,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Senay, Y.","contributorId":13534,"corporation":false,"usgs":true,"family":"Senay","given":"Y.","email":"","affiliations":[],"preferred":false,"id":490026,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mukhopadhyay, A.","contributorId":57762,"corporation":false,"usgs":true,"family":"Mukhopadhyay","given":"A.","email":"","affiliations":[],"preferred":false,"id":490027,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Szekely, F.","contributorId":79795,"corporation":false,"usgs":true,"family":"Szekely","given":"F.","email":"","affiliations":[],"preferred":false,"id":490029,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This report is the compilation for such features in the\r\nCentral and Eastern United States (CEUS), which for the purposes of the compilation, is\r\ndefined as the region extending from the Rocky Mountain Front eastward to the Atlantic\r\nseaboard. A key objective of this national compilation is to provide a comprehensive database\r\nof Quaternary features that might generate strong ground motion and therefore, should be considered\r\nin assessing the seismic hazard throughout the country. In addition to printed versions\r\nof regional and individual state compilations, the database will be available on the World-Wide\r\nWeb, where it will be readily available to everyone. The primary purpose of these compilations\r\nand the derivative database is to provide a comprehensive, uniform source of geological information\r\nthat can by used to complement the other types of data that are used in seismic-hazard\r\nassessments.\r\nWithin our CEUS study area, which encompasses more than 60 percent of the continuous U.S.,\r\nwe summarize the geological information on 69 features that are categorized into four classes\r\n(Class A, B, C, and D) based on what is known about the feature's Quaternary activity. The\r\nCEUS contains only 13 features of tectonic origin for which there is convincing evidence of\r\nQuaternary activity (Class A features). Of the remaining 56 features, 11 require further study in\r\norder to confidently define their potential as possible sources of earthquake-induced ground\r\nmotion (Class B), whereas the remaining features either lack convincing geologic evidence of\r\nQuaternary tectonic faulting or have been studied carefully enough to determine that they do not\r\npose a significant seismic hazard (Classes C and D).\r\nThe correlation between historical seismicity and Quaternary faults and liquefaction features\r\nin the CEUS is generally poor, which probably reflects the long return times between successive\r\nmovements on individual structures. Some Quaternary faults and liquefaction features\r\nare located in aseismic areas or where historical seismicity is sparse. These relations indicate\r\nthat the record of historical seismicity does not identify all potential seismic sources in the\r\nCEUS. Furthermore, geological studies of some currently aseismic faults have shown that the\r\nfaults have generated strong earthquakes in the geologically recent past. Thus, the combination\r\nof geological information and seismological data can provide better insight into potential\r\nearthquake sources and thereby, contribute to better, more comprehensive seismic-hazard\r\nassessments.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey,","doi":"10.3133/ofr00260","issn":"0094-9140","usgsCitation":"Crone, A.J., and Wheeler, R.L., 2000, Data for Quaternary faults, liquefaction features, and possible tectonic features in the Central and Eastern United States, east of the Rocky Mountain Front: U.S. Geological Survey Open-File Report 2000-260, 342 p., https://doi.org/10.3133/ofr00260.","productDescription":"342 p.","costCenters":[],"links":[{"id":155689,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":1541,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/ofr-00-0260/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c98f","contributors":{"authors":[{"text":"Crone, Anthony J. 0000-0002-3006-406X crone@usgs.gov","orcid":"https://orcid.org/0000-0002-3006-406X","contributorId":790,"corporation":false,"usgs":true,"family":"Crone","given":"Anthony","email":"crone@usgs.gov","middleInitial":"J.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":188895,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wheeler, Russell L. wheeler@usgs.gov","contributorId":858,"corporation":false,"usgs":true,"family":"Wheeler","given":"Russell","email":"wheeler@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":false,"id":188896,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This map is a synthesis of 32 new geologic maps encompassing the Littlefield 30' x 60' quadrangle, Arizona. Geologic information presented in this map and report may aid future land management decisions about land use, flood control, and environmental and range management programs for federal, state, and private agencies.

The map area is bordered on the north by the Utah-Arizona state line and is approximately 5 km east of the Nevada- Arizona state line (see map). The quadrangle is bounded by long 113? to 114? and lat 36?30' to 37?.

Magellan had the objectives of (1) improving knowledge of the geologic processes, surface properties, and geologic history of Venus by analysis of surface radar characteristics, topography, and morphology and (2) improving knowledge of the geophysics of Venus by analysis of venusian gravity. The Magellan spacecraft carried a 12.6-cm radar system to map the surface of Venus. The transmitter and receiver systems were used to collect three datasets: synthetic aperture radar (SAR) images of the surface, passive microwave thermal emission observations, and measurements of the backscattered power at small angles of incidence, which were processed to yield altimetric data. Radar imaging and altimetric and radiometric mapping of the venusian surface were done in mission cycles 1, 2, and 3, from September 1990 until September 1992. Ninety-eight percent of the surface was mapped with radar resolution of approximately 120 meters. The SAR observations were projected to a 75-m nominal horizontal resolution; these full-resolution data compose the image base used in geologic mapping. The primary polarization mode was horizontal-transmit, horizontal-receive (HH), but additional data for selected areas were collected for the vertical polarization sense. Incidence angles varied from about 20° to 45°. High-resolution Doppler tracking of the spacecraft was done from September 1992 through October 1994 (mission cycles 4, 5, 6). High-resolution gravity observations from about 950 orbits were obtained between September 1992 and May 1993, while Magellan was in an elliptical orbit with a periapsis near 175 kilometers and an apoapsis near 8,000 kilometers. Observations from an additional 1,500 orbits were obtained following orbitcircularization in mid-1993. These data exist as a 75° by 75° harmonic field.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/i2620","isbn":"0607938358","usgsCitation":"Bender, K.C., Senske, D.A., and Greeley, R., 2000, Geologic map of the Carson Quadrangle (V-43), Venus: U.S. Geological Survey IMAP 2620, 1 Plate: 50.52 x 33.55 inches; Purchasing information, https://doi.org/10.3133/i2620.","productDescription":"1 Plate: 50.52 x 33.55 inches; Purchasing information","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":438892,"rank":101,"type":{"id":30,"text":"Data Release"},"url":"https://doi.org/10.5066/P96Y411N","text":"USGS data release","linkHelpText":"Geologic map of the Carson Quadrangle (V-43), Venus"},{"id":6081,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/imap/2620/","linkFileType":{"id":5,"text":"html"}},{"id":186706,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/i2620.jpg"},{"id":280428,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/imap/2620/pdf/i2620.pdf"}],"scale":"5198991","otherGeospatial":"Venus","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b0ae4b07f02db69d2cb","contributors":{"authors":[{"text":"Bender, Kelly C.","contributorId":46410,"corporation":false,"usgs":true,"family":"Bender","given":"Kelly","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":272047,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Senske, David A.","contributorId":32975,"corporation":false,"usgs":true,"family":"Senske","given":"David","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":272046,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Greeley, Ronald","contributorId":20833,"corporation":false,"usgs":true,"family":"Greeley","given":"Ronald","email":"","affiliations":[],"preferred":false,"id":272045,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The map database represents the integration of previously published reports and new geologic mapping and field checking by the author (see Sources of Data index map on the map sheet or the Arc-Info coverage pi-so and the textfile pi-so.txt). The descriptive text (below) contains new ideas about the Hayward fault and other faults in the East Bay fault system, as well as new ideas about the geologic units and their relations.\r\n\r\nThese new data are released in digital form in conjunction with the Federal Emergency Management Agency Project Impact in Oakland. The goal of Project Impact is to use geologic information in land-use and emergency services planning to reduce the losses occurring during earthquakes, landslides, and other hazardous geologic events. The USGS, California Division of Mines and Geology, FEMA, California Office of Emergency Services, and City of Oakland participated in the cooperative project.\r\n\r\nThe geologic data in this report were provided in pre-release form to other Project Impact scientists, and served as one of the basic data layers for the analysis of hazard related to earthquake shaking, liquifaction, earthquake induced landsliding, and rainfall induced landsliding.\r\n\r\nThe publication of these data provides an opportunity for regional planners, local, state, and federal agencies, teachers, consultants, and others outside Project Impact who are interested in geologic data to have the new data long before a traditional paper map could be published. Because the database contains information about both the bedrock and surficial deposits, it has practical applications in the study of groundwater and engineering of hillside materials, as well as the study of geologic hazards and the academic research on the geologic history and development of the region.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/mf2342","usgsCitation":"Graymer, R., 2000, Geologic Map and Map Database of the Oakland Metropolitan Area, Alameda, Contra Costa, and San Francisco Counties, California (Online Version 1.0): U.S. Geological Survey Miscellaneous Field Studies Map 2342, Packages; Individual Files (Pamphlet: 31 p., Map: 35 x 49 inches); Database Files, https://doi.org/10.3133/mf2342.","productDescription":"Packages; Individual Files (Pamphlet: 31 p., Map: 35 x 49 inches); Database Files","additionalOnlineFiles":"Y","costCenters":[{"id":647,"text":"Western Earth Surface Processes","active":false,"usgs":true}],"links":[{"id":110100,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_29220.htm","linkFileType":{"id":5,"text":"html"},"description":"29220"},{"id":183657,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":9533,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/2000/2342/","linkFileType":{"id":5,"text":"html"}}],"scale":"50000","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.36749999999999,37.6175 ], [ -122.36749999999999,38 ], [ -122,38 ], [ -122,37.6175 ], [ -122.36749999999999,37.6175 ] ] ] } } ] }","edition":"Online Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6ae223","contributors":{"authors":[{"text":"Graymer, R.

Magellan had the objectives of (1) improving knowledge of the geologic processes, surface properties, and geologic history of Venus by analysis of surface radar characteristics, topography, and morphology and (2) improving knowledge of the geophysics of Venus by analysis of venusian gravity. The Magellan spacecraft carried a 12.6-cm radar system to map the surface of Venus. The transmitter and receiver systems were used to collect three datasets: synthetic aperture radar (SAR) images of the surface, passive microwave thermal emission observations, and measurements of the backscattered power at small angles of incidence, which were processed to yield altimetric data. Radar imaging and altimetric and radiometric mapping of the venusian surface were done in mission cycles 1, 2, and 3, from September 1990 until September 1992. Ninety-eight percent of the surface was mapped with radar resolution of approximately 120 meters. The SAR observations were projected to a 75-m nominal horizontal resolution; these full-resolution data compose the image base used in geologic mapping. The primary polarization mode was horizontal-transmit, horizontal-receive (HH), but additional data for selected areas were collected for the vertical polarization sense. Incidence angles varied from about 20° to 45°. High-resolution Doppler tracking of the spacecraft was done from September 1992 through October 1994 (mission cycles 4, 5, 6). High-resolution gravity observations from about 950 orbits were obtained between September 1992 and May 1993, while Magellan was in an elliptical orbit with a periapsis near 175 kilometers and an apoapsis near 8,000 kilometers. Observations from an additional 1,500 orbits were obtained following orbitcircularization in mid-1993.

This long-term study is a cooperative effort between the U.S. Geological Survey (USGS), the South Dakota Department of Environment and Natural Resources, and the West Dakota Water Development District, which represents various local and county cooperators. This map is part of a series of 1:100,000-scale maps for the study. The maps include a hydrogeologic map, structure-contour maps (altitudes of the tops of formations) for five formations that contain major aquifers in the study area, and potentiometric maps for these five major aquifers (the Inyan Kara, Minnekahta, Minnelusa, Madison, and Deadwood aquifers).<br />The study area consists of the topographically defined Black Hills and adjacent areas located in western South Dakota. The Black Hills area is an elongated, dome-shaped feature, about 125 miles long and 60 miles wide, which was uplifted during the Laramide orogeny (Feldman and Heimlich, 1980). The oldest geologic units in the study area are Precambrian metamorphic and igneous rocks, which are exposed in the central core of the Black Hills. Surrounding the Precambrian core is a layered series of sedimentary rocks including limestones, sandstones, and shales that are exposed in roughly concentric rings around the uplifted flanks of the Black Hills. The bedrock sedimentary units typically dip away from the uplifted Black Hills at angles that approach or exceed 10 degrees near the outcrops, and decrease with distance from the uplift. Many of the sedimentary units contain aquifers, both within and beyond the study area. Recharge to these aquifers occurs from infiltration of precipitation upon the outcrops and, in some cases, from infiltration of streamflow (Hortness and Driscoll, 1998).

This map is part of a series of 1:100,000-scale maps for the study. The maps include a hydrogeologic map, structure-contour maps (altitudes of the tops of formations) for five formations that contain major aquifers in the study area, and potentiometric maps for these five major aquifers (the Inyan Kara, Minnekahta, Minnelusa, Madison, and Deadwood aquifers).<br />The study area consists of the topographically defined Black Hills and adjacent areas located in western South Dakota. The Black Hills area is an elongated, dome-shaped feature, about 125 miles long and 60 miles wide, which was uplifted during the Laramide orogeny (Feldman and Heimlich, 1980). The oldest geologic units in the study area are Precambrian metamorphic and igneous rocks, which are exposed in the central core of the Black Hills. Surrounding the Precambrian core is a layered series of sedimentary rocks including limestones, sandstones, and shales that are exposed in roughly concentric rings around the uplifted flanks of the Black Hills. The bedrock sedimentary units typically dip away from the uplifted Black Hills at angles that approach or exceed 10 degrees near the outcrops, and decrease with distance from the uplift. Many of the sedimentary units contain aquifers, both within and beyond the study area. Recharge to these aquifers occurs from infiltration of precipitation upon the outcrops and, in some cases, from infiltration of streamflow (Hortness and Driscoll, 1998).
