Geospatial database for regional environmental assessment of central Colorado

Study focusing on the effects of historical mining on Forest Service lands in this area.

Info
Geochemical, modal, and geochronologic data for 1.4 Ga A-type granitoid intrusions of the conterminous United States

This report presents and makes data available to ongoing petrogenetic investigations of these rocks. It develops an accurate and current portrayal of their spatial distribution in GIS format while analyzed samples are presented via Excel workbooks.

Info
GIS and data tables for focus areas for potential domestic nonfuel sources of rare earth elements

Locations of focus areas to be used for planning and collection of geophysical, geological, and topographic (lidar) data pertaining to the study of rare earth element resources in the US.

Info
Basement domain map of the conterminous United States and Alaska

Seventy-seven major components of the North American continent were delineated at a general scale (1:5,000,000); including the general composition, geological environment, and types of primary metals endowments that can be expected in each domain.

Info
Prospect- and mine-related features on USGS topographic maps

Symbols indicating mining-related features digitized from historical USGS topographic maps in the western part of the conterminous US. Includes prospect pits, mine shafts and adits, quarries, open-pit mines, tailings piles and ponds, gravel and borrow pit
