This database of the New Castle 7.5 minute quadrangle, originally released as U.S Geological Survey Open-File Report 93-310 has been updated to include a digitized database.

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 Open-File report is a digital geologic map database. This digital map database is compiled from previously published sources combined with some new mapping and modifications in nomenclature. The geologic map database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U. S. Geological Survey. For detailed descriptions of the units, their stratigraphic relations and sources of geologic mapping consult Yerkes and Campbell (1993).

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.

This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area.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.

This CD-ROM publication provides a GIS analysis of a summaryterrane map, mineral deposit maps, and metallogenic belt maps forthe Russian Far East, Alaska, Canadian Cordillera and adjacentoffshore areas. This CD-ROM publication is one of a series ofpublications for a large collaborative project on the Major MineralDeposits, Metallogenesis, and Tectonics of the Russian Far East,Alaska, and the Canadian Cordillera. This project is providingcritical information for collaborators and customers on the majormetalliferous mineral resources, metallogenic patterns, and crustalorigin and evolution of mineralizing systems for the region. Themajor collaborating agencies for the project are the RussianAcademy of Sciences, ROSKOMNEDRA,...

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 of the Scotts Mills 7.5 minute quadrangle along the eastern margin of the Willamette Valley and adjacent lower foothills (Waldo and Silverton Hills) of the Cascade Range. The major emphasis of this investigation was to identify and map Columbia River Basalt Group (CRBG) units and to utilize this detailed CRBG stratigraphy to identify and characterize structural features. Together with the accompanying text file (geol.txt or geol.ps), it provides current information on the geologic structure and stratigraphy of the area covered. The...

This report provides background information on the regionalgeochemical data provided by the US Geological Survey to the USForest Service and Bureau of Land Management Interior ColumbiaBasin Ecosystem Management Project (ICBEMP). This report is one ina series of digital maps, data files, and reports generated by theUS Geological Survey to provide geologic process and mineralresource information to the Interior Columbia Basin EcosytemManagement Project. The various digital maps and data files arebeing used in a GIS-based ecosystem assessment including ananalysis of diverse questions relating to past, present, and futureconditions within the general area of the Columbia River Basin eastof the Cascade Mountains.
This report describes the contents of a digital dataset which consistsof four ARC/INFO Export format files. The dataset includes a digitalrepresentation of the Montana state geologic map.

Geologic data from a generalized geologic map of the Coeur d'Alene mining district by Gott and Cathrall (1980) was entered into a geographic information system (GIS) as part of a larger effort to create a regional digital geology for the Pacific Northwest. The map area is located in northern Idaho and extends across the state border into western Montana.
