The methodology employed a cluster-block technique. Sample areas were described based on a combination of helicopter-ground survey, aerial photointerpretation, and digital Landsat data. Major steps in the Landsat analysis involved preprocessing (geometric correction), derivation of statistical parameters for spectral classes, spectral class labeling of sample areas, preliminary classification of the entire study area using a maximum-likelihood algorithm, and final classification utilizing ancillary information such as digital elevation data.

Information gathered from recent field mapping of coal beds and from shallow, closely-spaced drill holes resulted in detailed coal bed correlations, which revealed another linear zone of en echelon faulting directly on the extended trend of the Lake Basin fault zone. This faulted area, referred to as the Sarpy Creek area, is located 48 km E of Hardin, Montana. It is about 16 km long, 13 km wide, and contains 21 en echelon normal faults that have an average strike of N 63oE. We therefore extend the Lake Basin fault zone 32 km farther SE than previously mapped to include the Sarpy Creek area. The Ash Creek oil field, Wyoming, 97 km due S of the Sarpy Creek area, produces from faulted anticlinal structues that have been interpreted to be genetically related to the primary wrench-fault system known as the Nye-Bowler fault zone. The structural similarities between the Sarpy Creek area and the Ash Creek area indicate that the Sarpy Creek area is a possible site for hydrocarbon accumulation.-from Authors","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mountain Geologist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"0027254X","usgsCitation":"Robinson, L.N., and Barnum, B.E., 1986, Southeastern extension of the Lake Basin fault zone in south- central Montana: implications for coal and hydrocarbon exploration ( USA).: Mountain Geologist, v. 23, no. 2, p. 37-44.","startPage":"37","endPage":"44","numberOfPages":"8","costCenters":[],"links":[{"id":223654,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"23","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b93dce4b08c986b31a708","contributors":{"authors":[{"text":"Robinson, L.

We hypothesize that the detergents form two distinct plumes, which consist of alkyl benzene sulfonates (ABS) detergents and linear alkyl sulfonates (LAS) and sodium dodecyl sulfate (NaLS) detergents. The ABS detergents were deposited from approximately 1940 through 1965, when ABS detergents were banned. From 1965 to the present, LAS and NaLS detergents were in the sewage. The ABS detergents appear to be transported in the aquifer at the same rate as the specific conductance (major cations and anions) and boron, which are currently used as conservative tracers of the plume of contaminated groundwater. There appears to be little or no biological degradation of the ABS detergents in the aquifer, based on their concentration in the plume. On the other hand, the LAS and NaLS detergents have degraded rapidly and have been detected only 0.6 km down gradient. The roleof the detergents in the transport of other organic compounds in the plume is nuclear. There is a separation of the ABS detergent plume and the volatile organic compound plume; however, the time of entry of the detergents and the volatile organic compounds is unknown. Therefore, it is not possible to conclude on the interaction of these two classes of compounds.&nbsp;</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0169-7722(86)90013-6","issn":"01697722","usgsCitation":"Thurman, E., Barber, L., and LeBlanc, D., 1986, Movement and fate of detergents in groundwater: A field study: Journal of Contaminant Hydrology, v. 1, no. 1-2, p. 143-161, https://doi.org/10.1016/0169-7722(86)90013-6.","productDescription":"19 p.","startPage":"143","endPage":"161","numberOfPages":"19","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":224229,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5f0ee4b0c8380cd70d47","contributors":{"authors":[{"text":"Thurman, E.M.","contributorId":102864,"corporation":false,"usgs":true,"family":"Thurman","given":"E.M.","affiliations":[],"preferred":false,"id":369801,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barber, L.B.

Eight methods for estimating these parameters have been evaluated by R. J. Gilliom and D. R. Helsel (this issue) using Monte Carlo simulations. To verify those findings, the same methods are now applied to actual water quality data. The best method (lowest root-mean-squared error (rmse)) over all parameters, sample sizes, and censoring levels is log probability regression (LR), the method found best in the Monte Carlo simulations. Best methods for estimating moment or percentile parameters separately are also identical to the simulations. Reliability of these estimates can be expressed as confidence intervals using rmse and bias values taken from the simulation results. Finally, a new simulation study shows that best methods for estimating uncensored sample statistics from censored data sets are identical to those for estimating population parameters. Thus this study and the companion study by Gilliom and Helsel form the basis for making the best possible estimates of either population parameters or sample statistics from censored water quality data, and for assessments of their reliability.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR022i002p00147","usgsCitation":"Helsel, D., and Gilliom, R.J., 1986, Estimation of distributional parameters for censored trace level water quality data: 2.

These tephra deposits (1) record numerous explosive eruptions, (2) form important regional time-stratigraphic marker beds, and (3) record repeated changes in composition within and between eruptive periods. Recognized tephra strata record more than 100 explosive eruptive events at Mount St. Helens; those tephra strata are classified as beds, layers, and sets. Tephra sets, each of which consists of a group of beds and layers, define in part the nine eruptive periods recognized at the volcano. Individual tephra sets are distinguished from stratigraphically adjacent sets by differences in composition or by evidence of clapsed time. Several tephra units from Mount St. Helens form important marker beds at distances of hundreds of kilometers downwind from the volcano. Cummingtonite phenocrysts, which are known in ejecta from only Mount St. Helens in the Pacific Northwest, characterize some marker beds and readily identify their source. The tephra sequence also records eruption of the mafic andesites that mark the appearance of the modern Mount St. Helens and numerous changes in composition among dacite, basalt, and andesite since that time. ?? 1986 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of Volcanology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF01073510","issn":"02588900","usgsCitation":"Mullineaux, D.R., 1986, Summary of pre-1980 tephra-fall deposits erupted from Mount St. Helens, Washington State, USA: Bulletin of Volcanology, v. 48, no. 1, p. 17-26, https://doi.org/10.1007/BF01073510.","startPage":"17","endPage":"26","numberOfPages":"10","costCenters":[],"links":[{"id":223958,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205433,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01073510"}],"volume":"48","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9ea1e4b08c986b31e024","contributors":{"authors":[{"text":"Mullineaux, D.

Geologic and isotopic evidence demonstrates that the ore-forming fluids were in chemical equilibrium with the Proterozoic metavolcanic and metasedimentary host-rock terrane at depth and that the metals, sulfur, and carbonate deposited in the fractures were derived from the metamorphic rocks. The data are not consistent with chemical contributions from an unrecognized magma or from the overlying Phanerozoic sedimentary rocks. The protoliths for the metamorphic rocks were submarine volcanic rocks and related volcanogenic exhalative iron-formations and chert. Water trapped along the basement faults and in the regolith between the basement and the overlying Paleozoic sedimentary rocks interacted with the metavolcanic rocks to produce isotopically heavy fluids containing high concentrations of dissolved metals and carbonate. Calculated delta&nbsp;</span><sup>18</sup><span>&nbsp;O values for this fluid range from 4.3 to 8.2 per mil, indicating a low water/rock ratio in the source terrane.Two stages of alteration and three stages of vein mineralization are recorded in the Schwartzwalder deposit. At the onset of Laramide faulting, fluids migrated along the fracture systems to zones of low hydraulic potential. These fluids contained CO&nbsp;</span><sub>2</sub><span>&nbsp;and had a metastably large K/Na ratio; they altered the gneissic wall rocks to a carbonate-sericite assemblage, adding K (super +) and CO&nbsp;</span><sub>2</sub><span>&nbsp;and removing SiO&nbsp;</span><sub>2</sub><span>&nbsp;with little or no change in volume. As the fractures continued to open, CO&nbsp;</span><sub>2</sub><span>&nbsp;was evolved from the fluids, increasing the pH and superimposing a hematite-adularia alteration assemblage on the earlier alteration.The veins record three stages of mineralization, the second of which generated the high-grade uranium veins. Evidence for the stage I sulfide-carbonate mineralization is poorly preserved, but isotopic and temperature data from this stage are consistent with a trend in fluid composition culminating in stage II pitchblende deposition. Sudden, large movements along the faults caused episodic evolution of CO&nbsp;</span><sub>2</sub><span>&nbsp;from the fluid. This loss of CO&nbsp;</span><sub>2</sub><span>&nbsp;decreased the solubilities of carbonates and adularia and the stabilities of sulfur species in solution. Uranyl carbonate complexes dissociated and sulfur species in solution likely reduced the uranyl ions to produce stage II pitchblende. Carbonate, adularia, and sulfides dominated the vein mineralogy after deposition of pitchblende. Progressively lower delta&nbsp;</span><sup>18</sup><span>&nbsp;O values in vein carbonates suggest the mixing of cooler, less evolved, perhaps meteoric, waters during the later stages of mineralization. However, the fluid pressure remained high, as indicated by explosion breccias and inward collapse features which formed as fault movements produced sudden decreases in the confining pressure. Only the stage III carbonate-iron disulfide assemblage in the major postore segment of the Illinois fault may be the product of meteoric water alone.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.81.4.872","issn":"03610128","usgsCitation":"Wallace, A.R., and Whelan, J.F., 1986, The Schwarzwalder uranium deposit, III: Alteration, vein mineralization, light stable isotopes, and genesis of the deposit: Economic Geology, v. 81, no. 4, p. 872-888, https://doi.org/10.2113/gsecongeo.81.4.872.","productDescription":"17 p.","startPage":"872","endPage":"888","numberOfPages":"17","costCenters":[],"links":[{"id":225855,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"81","issue":"4","noUsgsAuthors":false,"publicationDate":"1986-07-01","publicationStatus":"PW","scienceBaseUri":"505ba8dde4b08c986b321ed9","contributors":{"authors":[{"text":"Wallace, A.
