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 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 data set represents reconnaissance geologic mappingof the Christian quadrangle, Alaska. It is used tocreate the mapsheet in USGS OFR 00-192, which showsbedrock and surficial deposits of the 1:250,000 scaleChristian quadrangle in northern Alaska.

This database and accompanying text depict historical and modern reported occurrences of petroleum both in wells and at the surface within the boundaries of the Central Alaska Province. These data were compiled from previously published and unpublished sources and were prepared for use in the 2002 U.S. Geological Survey petroleum assessment of Central Alaska, Yukon Flats region. Indications of petroleum are described as oil or gas shows in wells, oil or gas seeps, or outcrops of oil shale or oil-bearing rock and include confirmed and unconfirmed reports. The scale of the source map limits the spatial resolution (scale) of the database to 1:2,500,000 or smaller.

This data set is a point coverage representing Alaskan coal fields of undetermined extent. Resolution of data is 1:5000000. The points were collected from Farrell Barnes's "Coal Fields of the United States, Alaska"(sheet 2, 1960) map. Updates are planned for the future. These updates will include the polygons used by energy resource regions of the USGS Energy Program in the National Coal Assessment. Data from Alaska will be incorporated using the most recent digital data available from Alaskan authorities.
