This is a point coverage that contains data for coal and otherstratigraphic horizons in the John Henry Member of the StraightCliffs Formation (Upper Cretaceous) east of 112 degrees oflongitude in the Kaiparowits Plateau. The item map# is the numberon the index map (Figure A, Plate 1) that refers to a record in adata table (Appendix 1) in Hettinger and others (1996). Bufferswere drawn at a three-mile distance from data points in thiscoverage to create the reliability coverage. This coverage alsoincludes arcs representing lines of cross section shown in Figs. B,C, D and E, Plate 1 (Hettinger and others, 1996).

The paper version of the Geologic Map of the eastern part of the Challis National Forest and vicinity, Idaho was compiled by Anna Wilson and Betty Skipp in 1994. The geology was compiled on a 1:250,000 scale topographic base map. TechniGraphic System, Inc. of Fort Collins Colorado digitized this map under contract for N.Shock. G.Green edited and prepared the digital version for publication as a GIS database. The digital geologic map database can be queried in many ways to produce a variety of geologic maps.

During the Pliocene to middle Pleistocene, pluvial lakes in the western Great Basin repeatedly rose to levels much higher than those of the well-documented late Pleistocene pluvial lakes, and some presently isolated basins were connected. Sedimentologic, geomorphic, and chronologic evidence at sites shown on the map indicates that Lakes Lahontan and Columbus-Rennie were as much as 70 m higher in the early-middle Pleistocene than during their late Pleistocene high stands. Lake Lahontan at its 1400-m shoreline level would submerge present-day Reno, Carson City, and Battle Mountain, and would flood other now-dry basins. To the east, Lakes Jonathan (new name), Diamond, Newark, and Hubbs also reached high stands during...

Alska is a complex amalgamation of tectonic blocks with diverse histories. Sedimentary basins that are formed on these blocks both before amalgamation and as a result of collisions between them record the tectonic history of this complex region. Thermal-maturity data-indicators of maximum burial temperatures-provide important constraints both on basin evolution and on terrane amalgamation. To help elucidate these relations, and to provide constraints for hydrocarbon assessments, the U.S. Geological survey (USGS) has compilied thermal-maturity data from Alaska for many decades. This report is a digital release of our current understanding of thermal-maturity patters in Alaska.

This digital map database, which is compiled from previouslyunpublished and open-filed U.S. Geol. Survey reports (Wesling andHelley, 1989), represents the general distribution and identity ofQuaternary deposits in eight 7.5 minute quadrangles in the southernSan Francisco Bay region, California.

This cover contains faults in the unconformity at the Cambrian-Precambrianboundary. These data were contributed byGlenn Bear of Indiana University as part of the work onhis doctoral thesis. The southern part of the map was produced byJames Drahovzal of the Kentucky Geological Survey and merged withBear's map of the rest of the map area and beyond.Public and proprietary seismic reflection and welldata were used to define the basement structure.A prominent east-west structure in the southern half of the maparea is the western end of the Rough Creek Graben. At its deepestpoint the unconformity is more than 30,000 ft(9,100 m) below sea level. Faulted strata at this depth mean thatthe Rough Creek Fault System penetrates...

The northern part of the map area and large adjacent regions havebeen severely shaken by one or more moderate to large prehistoricearthquakes. The evidence of these takes the form ofpaleoliquefaction features, including shaking-induced sandblows anddikes that fed them.Over several summer field seasons from 1990 through 1994,several workers searched ditches and river banks for evidenceof liquefaction. They found numerous dikes and sandblows.This database includes the locations and descriptions of dikes theyobserved and measured.The most widespread paleoliquefaction is attributed to amid-Holocene earthquake near what is now Vicennes, IN, with anestimated moment- magnitude of about 7.5. Stratigraphic,geomorphological,...

The evidence of these takes the form of paleoliquefactionfeatures, including shaking-induced sandblows and dikes that fed them.Over several summer field seasons between 1990 and 1994, Cheryl andPat Munson, along with several of their students, searched ditchesand river banks for evidence of liquefaction. They found numerousbanks with shaking-induced sandblows and the dikes that fed them.This database includes the location of dikes thatthe Munsons and those with them observed and measured.

This Open-File report is a digital geologic map database. Thisdigital map database is compiled from previously published sourcescombined with some new mapping and modifications in nomenclature.The geologic map database delineates map units that are identifiedby general age and lithology following the stratigraphicnomenclature of the U. S. Geological Survey. For detaileddescriptions of the units, their stratigraphic relations, sourcesof geologic mapping, and data on exploratory wells consult Yerkes(1997), and Yerkes and Showalter (1990).

This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area. Together with the accompanying text file (cdbegeo.txt or cdbegeo.ps), it provides current information on the geologic structure and stratigraphy of the area covered. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution (scale) of the database to 1:24,000 or smaller.

Unpublished mineral assessment reports of the Colville andOkanogan national forests (Chelan, Ferry, Okanogan, PendOreille, Skagit, Stevens, and Whatcom counties, WA) containdata on 3,934 samples analyzed for gold, silver, copper, lead,zinc, molybdenum, tungsten and uranium. Data presented herewere obtained by R.A. Grant (1982a,b) for an assessment ofthe mineral potential of these national forests during1979-1982 under a contract from the USDA-Forest Service.

Permits to explore for and (or) develop mineral resources onFederal lands can be used to indicate locations and types ofmineral-related activities on national forests. Permits for theseactivities require filing of a Notice of Intent to conduct mineralexploration activities and (or) a Plan of Operation, ifsignificant land disturbance results. This compilation of noticesand plans for the Colville, Kaniksu, Okanogan, and Wenatcheenational forests between 1967 and 1998 is intended for use incombination with geologic and economic information to predictfuture mineral-related activities in the region.
