This map of the Richfield 1° x 2° quadrangle shows the regional distribution of bismuth and cadimum in the less-than-0.180-mm (minus-80-mesh) fraction of stream sediments. It is part of a folio of maps of the Richfield 1° x 2° quadrangle, Utah, prepared under the Conterminuous United States Mineral Assessment Program. Other published geochemical maps in this folio are listed in the references (this publication).
\nThe Richfield quadrangle is located in west-central Utah and includes the eastern part of the Pioche-Marysvale igneous and mineral belt, which extends from the vicinity of Pioche in southeastern Nevada, east-northeastward for 155 miles into central Utah. The western two-thirds of the Richfield quadrangle is part of the Basin and Range province, whereas the eastern third is part of the High Plateaus of Utah, a subprovince of the Colorado Plateau.
\nBedrock in the northern part of the Richfield quadrangle consists predominantly of Late Proterozoic and Paleozoic sedimentary strata that were thrust eastward during the Sevier orogeny in Cretaceous time onto an autochthon of Mesozoic sedimentary rocks located in the eastern part of the quadrangle. The southern part of the quadrangle is largely underlain by Oligocene and younger volcanic rocks and related intrusions. Extensional tectonism in late Cenozoic time broke the bedrock terrain into a series of north-trending fault blocks; the uplifted mountain areas were eroded to various degrees and the resulting debris was deposited in adjacent basins. Most of the mineral deposits in the Pioche-Marysvale mineral belt were formed as a result of igneous activity in the middle and late Cenozoic time. A more complete description of the geology and a mineral-resource appraisal of the Richfield quadrangle appears in Steven and Morris (1984 and 1987).
\nThe regional sampling program was designed to define broad geochemical patterns and trends that can be utilized along with geological and geophysical data to assess the mineral-resource potential for this quadrangle. Reconnaissance geochemical surveys are valuable tools in mineral exploration, especially when used in conjunction with data obtained from other earth science disciplines. Identifying specific exploration targets generally involves additional, more detailed investigations.

The volcano is a superb outdoor laboratory for studying volcanic processes, deposits of observed events, and deposits whose origins are inferred by classic geologic techniques, including analogy to recent deposits. During the past 4,500 years, Mount St. Helens has been more active and more explosive than any other volcano in the conterminous United States. \r\nMount St. Helens became active in mid-March 1980, and eruptive activity began on March 27. Since the climactic eruption of May 18, 1980, the volcano has continued to be active at least until 1988. The 1890 activity of Mount St. Helens is summarized in U.S. Geological Survey Professional Papers 1249 and 1250. \r\n\r\nThis road guide is a tour of Mount St. Helens volcano and vicinity, with emphasis on the effects and deposits of the 1980 eruption. The road log starts from the U.S. Geological Survey's David A. Johnston Cascades Volcano Observatory, Vancouver, Washington. The guide is organized around two primary routes. LEG I is on paved and gravel roads from Vancouver to areas east of Mount St. Helens, including Windy Ridge Overlook near Spirit Lake. This is possibly the most scenic route described in the guide, including a transect of the devastated zone of May 18, 1980, Spirit Lake, and numerous vistas of the volcano. LEG II leads to areas west of the volcano from Vancouver via U.S. Interstate Highway 5, then on a paved ... road along the Toutle River. Highlights include the spectacular effects of mudflows and a view of the huge debris-avalanche deposit that was formed on May 18, 1980.","language":"ENGLISH","publisher":"U.S. G.P.O. ; For sale by the Books and Open-File Reports Section, U.S. Geological Survey,","doi":"10.3133/b1859","usgsCitation":"Doukas, M.P., 1990, Road guide to volcanic deposits of Mount St. Helens and vicinity, Washington: U.S. Geological Survey Bulletin 1859, v, 53 p. :ill. ;28 cm., https://doi.org/10.3133/b1859.","productDescription":"v, 53 p. :ill. ;28 cm.","costCenters":[],"links":[{"id":3390,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://vulcan.wr.usgs.gov/Volcanoes/MSH/NatMonument/RoadGuide/framework.html","linkFileType":{"id":5,"text":"html"}},{"id":166237,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/bul/1859/report-thumb.jpg"},{"id":62160,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/bul/1859/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0fe4b07f02db5fed5e","contributors":{"authors":[{"text":"Doukas, Michael P. mdoukas@usgs.gov","contributorId":2686,"corporation":false,"usgs":true,"family":"Doukas","given":"Michael","email":"mdoukas@usgs.gov","middleInitial":"P.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":212683,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":27954,"text":"wri894162 - 1990 - Lithology of basin-fill deposits in the Albuquerque-Belen basin, New Mexico","interactions":[],"lastModifiedDate":"2023-03-14T21:47:58.818772","indexId":"wri894162","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1990","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"89-4162","title":"Lithology of basin-fill deposits in the Albuquerque-Belen basin, New Mexico","docAbstract":"Sediments that fill the Albuquerque-Belen basin in central New Mexico comprise an aquifer that supplies water to approximately one-third the population of the State. Analysis of driller 's logs and geophysical logs indicate that an area of fine-grained deposits generally underlies the west-central part of the basin. Coarse-grained deposits are concentrated primarily along the axis of the north-central part of the basin. Mixed lithologic textures are present in the rest of the basin and are especially pronounced in the east-central part. Lithologic interpretation of borehole-geophysical logs were used to construct 10 lithologic sections. These sections show that the upper part of the basin fill consists mostly of sandy lenses alternating with clayey or silty lenses.

The target was gold mineralization in high-alumina alteration zones of the type that occurs in the Carolina Slate Belt, eastern United States. Such a target was sought in the Ad Darb area because of the known presence of kyanite in schist of the Sabya formation, which was interpreted to be a possible indicator of late Proterozoic high-alumina hydrothermal activity in the region.
\nOverall, metal values in the wadi-sediment samples are low. The known kyanite mineral occurrence is marked by anomalous gold and tin in three minus-80-mesh samples. The low values of the metals do not justify further exploration for the sought deposit type in the immediate vicinity, although the signature of anomalous elements in the wider region is comparable to the signature known in the Carolina Slate Belt, and is permissive of the interpretation that a diffuse hydrothermal system operated in the region during the late Proterozoic. A large concentration of polymetallic anomalies (gold, arsenic, copper, antimony, tin, tungsten, and lead) is outlined in the northeastern part of the survey area on the basis of panned-concentrate samples. The source of the concentration is unknown, and further investigations are recommended. Recommended low-priority investigation of the source of lead and zinc anomalies in the western part of the survey area would be justified as part of a larger program designed to evaluate the mineral potential of the entire belt of Sabya formation rock.

Water-level and water-quality data were compared with similar data collected during previous investigations conducted during 1976-83 to determine long-term effects of surface mining on the hydrologic system. Before mining, the watersheds were characterized by sequences of flat-lying sedimentary rocks containing two major coal seams and underclays. An aquifer was present above each of the underclays. Surface mining removed the upper aquifer, stripped the coal seam, and replaced the sediment. This created a new upper aquifer with different hydraulic and chemical characteristics. Mining did not disturb the middle aquifer. A third, deeper aquifer in each watershed was not studied.
Water levels were continuously recorded in one well in each aquifer. Other wells were measured every 2 months. Water levels in the upper aquifers reached hydraulic equilibrium from 2 to 5 years after mining ceased. Water levels in the middle aquifers increased more than 5 feet during mining and reached equilibrium almost immediately thereafter.
Water samples were collected from three upper-aquifer well, a seep from the upper aquifer, and the stream in each watershed. Two samples were collected in 1986 and 1987, and one each in 1988 and 1989. In both watersheds, sulfate replaced bicarbonate as the dominant upper-aquifer and surface-water anion after mining.
For the upper aquifer of a watershed located in Muskingum County, water-quality data were grouped into premining and late postmining time periods (1986-89). The premining median pH and concentration of dissolved solids and sulfate were 7.6, 378 mg/L (milligrams per liter), and 41 mg/L, respectively. The premining median concentrations of iron and manganese were 10 μg/L (micrograms per liter) and 25 μg/L, respectively. The postmining median values of pH, dissolved solids, and sulfate were 6.7, 1,150 mg/L, and 560 mg/L, respectively. The postmining median concentrations of iron and manganese were 3,900 μg/L and 1,900 μg/L, respectively.
For the upper aquifer of a watershed located in Jefferson County, the water-quality data were grouped into three time periods of premining, early postmining, and late postmining. The premining median pH and concentrations of dissolved solids and sulfate were 7.0, 335 mg/L, and 85 mg/L, respectively. The premining median concentrations of iron and manganese were 30 μg/L for each constituent. Late postmining median pH and concentrations of dissolved solids and sulfate were 6.7, 1,495 mg/L, and 825 mg/L, respectively. The postmining median concentrations of iron and manganese were 31 μg/L and 1,015 μg/L, respectively. Chemistry of water in the middle aquifer in each watershed underwent similar changes.
In general, statistically significant increases in concentrations of dissolved constituents occurred because of surface mining. In some constituents, concentrations increased by more than an order of magnitude. The continued decrease in pH indicated that ground water had no reached geochemical equilibrium in either watershed more than 8 years after mining.

Since 1969, at least 90 large-capacity wells have been drilled, of which 57 were public supply wells, 23 were irrigation wells, and 10 were industrial wells. All but seven of the new public-supply wells are located in the northeastern part of the county.
\nThe withdrawal of ground water in Fort Bend County increased from 56 million gallons per day in 1969 to 72 million gallons per day in 1982, and then decreased to 53 million gallons per day in 1986. Withdrawals for public supply increased from 4 million gallons per day in 1969 to 28 million gallons per day in 1986. Withdrawals for irrigation averaged 38 million gallons per day during 1969-82 and in 1984, but averaged 20 million gallons per day in 1983, 1985, and 1986. Withdrawals for industrial use declined from 13 million gallons per day in 1969 to 5 million gallons per day in 1986.
\nWater levels in wells screened in the upper unit of the Chicot aquifer generally fluctuated less than 4 feet between 1968-69 and 1987. During the same period, water-level declines in wells screened in the lower unit of the Chicot aquifer ranged from less than 10 feet in most of the western part of the county to 100 feet in the northeastern corner. In the southwestern part of the county, the decline was less than 20 feet. Hydrographs of wells completed in the lower unit of the Chicot showed that water levels continued to decline from 1969 to the early 1980's. The hydrographs of wells located outside of the northeast area generally show a stabilization of water levels corresponding to the reduction in withdrawals after 1982 in Fort Bend County and in the neighboring Houston metropolitan area to the northeast.
\nWithdrawals from the Evangeline aquifer increased from 15 percent of the total in 1969 to 50 percent in 1986. Water-level declines in wells screened in the Evangeline aquifer during the same period ranged from less than 25 feet in the northwestern part of the county to 125 feet in the northeastern part. In the southwestern one-quarter of the county, the decline was less than 50 feet.
\nDeclines in the potentiometric surfaces of the aquifers have caused compaction of clay resulting in land-surface subsidence. Between 1906 and 1978, about 65 percent of the county subsided more than 0.5 foot. Studies in the Houston area have shown that most clay compaction occurs in the Chicot aquifer and that the compressibility of the clays increases towards the coast. The total thickness of clays in the Chicot aquifer increases from less than 150 feet in the northwestern part of Fort Bend County to more than 350 feet along the eastern border. The total thickness of clay in the Evangeline aquifer increases from an average of about 700 feet in the northwest to about 1,100 feet in the east. The northeastern part of Fort Bend County is most susceptible to future subsidence because it is the area where the largest water-level declines have occurred and where the thickest, most compressible clays in the county are found.
\nThe concentrations of dissolved solids in water from wells in Fort Bend County have not changed appreciably from 1969 to 1987. The median concentrations of dissolved solids are 475 milligrams in water from wells in Fort Bend per liter in water from the upper unit of the Chicot aquifer, 337 milligrams per liter in water from the lower unit of the Chicot aquifer, and 307 milligrams per liter in water from the Evangeline aquifer.

Transmissivities generally range from 500 to 10,000 feet squared per day, and theoretical well yields generally range from 100 to 900 gallons per minute.
\nRegional ground-water flow in the confined-drift aquifers is to the southeast with local discharge to the East and Middle Branches of the Chippewa River, the North Fork Crow and Sauk Rivers, and to smaller streams, lakes, wetlands, and wells. Water levels near high-capacity pumped wells generally fluctuate 5 to 40 feet annually, compared to annual fluctuations of less than 5 feet in the unconfined aquifer.
\nWater from confined-drift aquifers generally is suitable for most uses. The water is hard to very hard and contains locally elevated concentrations of iron, manganese, and dissolved solids.
\nResults from a ground-water-flow model indicate that increased pumping from confined aquifers in the area would not adversely affect water levels. The addition of 10 to 20 hypothetical wells, pumping 123 to 246 million gallons per year, generally resulted in regional water-level declines of 0.1 to 1.0 feet. Simulations showed that the reduced recharge and increased pumping resulting from a 3-year drought probably would lower water levels between 5 and 10 feet regionally in the confined-drift aquifers and as much as 20 feet locally in the unconfined aquifer. Ground-water discharge to the East Branch Chippewa and North Fork Crow Rivers during the simulated drought would be reduced by 38 percent of 1984 conditions.

Fieldwork was carried out in 1986-88 by the U.S. Bureau of Mines and the U.S. Geological Survey to appraise the identified (known) resources and assess the mineral resource potential (undiscovered) of the wilderness study area. Within the Wabayuma Peak Wilderness Study Area are 14 private parcels of land totaling 1,315 acres. The Wabayuma Peak Wilderness Study Area, including the 14 private parcels of land, is herein referred to as the 'wilderness study area' or the 'study area'. The Boriana, Antler, and Copper World mines lie near the east boundary of the study area. The Boriana mine was a major tungsten-producing mine of the United States during World War II. The Antler and Copper World mines produced relatively small amounts of copper and zinc prior to 1970.\r\n\r\nCopper and zinc were mined within 100 ft of the study area at the Antler mine. The Antler mine contains subeconomic resources of 350,000 to 400,000 short tons of copper-zinc ore; a minimum of 2,000 short tons, at grades of 1 to 4 percent copper and 1 to 2 percent zinc, lie within the study area. No other mineral resources were identified within the study area.\r\n\r\nFour small tracts in the eastern part and one in the central part of the study area have high resource potential for copper, zinc, and minor lead, silver, and gold in massive sulfide deposits. A large central tract and two eastern tracts have moderate resource potential for the same metals. An eastern and a western tract within the wilderness study area have high resource potential for tungsten, copper, and combinations of beryllium, gold, silver, arsenic, bismuth, molybdenum, tin, indium, thorium, niobium, yttrium, lanthanum, scandium, tantalum, rhenium, lead, zinc, and iron in granite-related tungsten-polymetallic vein deposits. Most of the rest of the study area has moderate resource potential for these metals. A northern tract in the study area has moderate resource potential for gold, copper, and combinations of silver, zinc, lead, tungsten, and molybdenum in polymetallic vein deposits of several types.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/b1737E","usgsCitation":"Conway, C.M., Hassemer, J.R., Knepper, D.H., Pitkin, J.A., Jachens, R.C., and Chatman, M.L., 1990, Mineral Resources of the Wabayuma Peak Wilderness Study Area, Mohave County, Arizona: U.S. Geological Survey Bulletin 1737, Report: viii, E1-E52; 1 plate in pocket, https://doi.org/10.3133/b1737E.","productDescription":"Report: viii, E1-E52; 1 plate in pocket","additionalOnlineFiles":"Y","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":135733,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/bul/1737e/report-thumb.jpg"},{"id":84422,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/bul/1737e/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":84423,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/bul/1737e/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.5,34.583333333333336 ], [ -114.5,35.25 ], [ -113.5,35.25 ], [ -113.5,34.583333333333336 ], [ -114.5,34.583333333333336 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db6357de","contributors":{"authors":[{"text":"Conway, Clay M.","contributorId":106860,"corporation":false,"usgs":true,"family":"Conway","given":"Clay","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":235500,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hassemer, Jerry R.","contributorId":79448,"corporation":false,"usgs":true,"family":"Hassemer","given":"Jerry","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":235497,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Knepper, Daniel H. dknepper@usgs.gov","contributorId":1242,"corporation":false,"usgs":true,"family":"Knepper","given":"Daniel","email":"dknepper@usgs.gov","middleInitial":"H.","affiliations":[],"preferred":true,"id":235496,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pitkin, James A.","contributorId":96651,"corporation":false,"usgs":true,"family":"Pitkin","given":"James","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":235498,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Jachens, Robert C. jachens@usgs.gov","contributorId":1180,"corporation":false,"usgs":true,"family":"Jachens","given":"Robert","email":"jachens@usgs.gov","middleInitial":"C.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":235495,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Chatman, Mark L.","contributorId":97878,"corporation":false,"usgs":true,"family":"Chatman","given":"Mark","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":235499,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}} ,{"id":57205,"text":"ofr90350 - 1990 - Hydrography of the Gulf of Maine and Massachusetts Bay, data report for R/V OCEANUS cruise 181, 5-15 February 1987","interactions":[],"lastModifiedDate":"2016-06-21T13:58:49","indexId":"ofr90350","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1990","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":"90-350","title":"Hydrography of the Gulf of Maine and Massachusetts Bay, data report for R/V OCEANUS cruise 181, 5-15 February 1987","docAbstract":"This report presents hydrographic data obtained on R/V OCEANUS Cruise 181 from February 5-15, 1987. The hydrographic measurements (pressure, temperature, salinity, oxygen, beam attenuation, phosphate, silicate and nitrate/nitrite) were obtained in Georges, Jordan, and Wilkinson Basin in the Gulf of Maine and directly east of Boston across Massachusetts Bay as part of a study of currents and sediment transport in this region (figure 1).
\nDuring Cruise 181, a total of 95 hydrographic profiles were obtained by means of a conductivity-temperature-depth (CTD) profiler. Stations are numbered sequentially and station information is tabulated in table 1. The stations were arranged in ten transects (figure 1). Section 1 was across the Great South Channel and section 7 was across the Northeast Channel--the two main oceanic entrances and exits of the Gulf of Maine. Section 2 was along a saddle (Rodgers Pass) separating Wilkinson Basin from Georges Basin. Sections 3,5, and 10 were across different regions of Wilkinson Basin and all intersected at the longterm mooring site W1 in the center of Wilkinson Basin; section 8 was a dog-leg section through the southern portion of Jordan Basin; and sections 6 (east-west) and 9 (north-south) were within Georges Basin. A severe winter storm (see table 2 and 3) occurred between February 9 and 10 and work was stopped while the OCEANUS rode out the storm in Cape Cod Bay and repaired storm damage. Section 4 across Massachusetts Bay and section 5 across Wilkinson Basin, were repeated twice, once before the storm (sections 4a and 5a) and once after the storm (sections 4b and 5b).

The aquifer is present throughout Iowa and is confined beneath other aquifers in much of the State. Information on the aquifer available from drillers and contractors, provided estimates of aquifer transmissivity values ranging from about 500 to about 3,000 square feet per day. The largest transmissivity values are for dolomite and dolomite-cemented sandstone, indicating that permeability in much of the aquifer is due to secondary fractures. The aquifer is vertically bounded by an upper leaky confining unit with a vertical hydraulic conductivity of 10-10 feet per second.
\nThe aquifer was simulated using a two-layer finite-difference ground-water flow model. The upper layer simulated a source bed in aquifers composed of Silurian and Devonian rocks overlying the St. Peter-Jordan aquifer. The lower layer simulated flow in the St. Peter-Jordan aquifer. Lateral boundaries assigned in the model include constant heads in northeastern Iowa, where the aquifer is in contact with the Mississippi River or is unconfined, and no-flow boundaries in western and northwestern Iowa, where the rocks are insufficiently permeable to form an aquifer. The aquifer boundaries to the north, east, and south of Iowa were determined by geohydrologic conditions and the relation of the St. Peter-Jordan aquifer with the lateral extent of adjacent aquifers.
\nAn assumption that the largest part of recharge to the aquifer is from outcrop areas in northeastern Iowa and from Minnesota is not supported by the results of this study. Vertical leakage from overlying rocks accounted for most of the recharge to the aquifer in northwestern Iowa. Discharge is mostly through lateral boundaries and to rivers.
\nPumping has caused changes in the flow system that include regional declines in the potentiometric surface of the aquifer. Simulation indicates that pumping through 1980 increased net vertical leakage into the aquifer to about double the predevelopment rate. Discharge across lateral boundaries has been substantially reduced or reversed by pumping. Aquifer storage provided about one-third of the water required to supply pumping in the 1970's. Simulation of future conditions, assuming no increase in pumping rates, indicates that the rate of decline in water levels will decrease by the year 2020. As equilibrium with pumping is approached in 2020, 75 percent of the pumpage will be balanced by vertical leakage, eight percent by water released from aquifer storage, and 17 percent by increases in boundary recharge or decreases in boundary discharge. Future pumping at an increasing rate of about 10 percent per decade of the average pumping rate in 1975 will require about one and one-half times the vertical leakage of the 1971-1980 period and about fivetimes the net inflow from lateral boundaries; however, the rate of water released from aquifer storage will be about half the 1970's rate. Under these conditions, the head in the aquifer will continue to decline at an almost constant rate until 2020.
