Mineral Resources On-Line Spatial Data
Automated mapping of mineral groups and green vegetation from Landsat Thematic Mapper imagery with an example from the San Juan Mountains, Colorado Analysis of multispectral satellite imagery allows us to identify areas covered by various types of minerals and vegetation, with results provided in image files you can use in GIS.
Resource potential and geology of the Grand Mesa, Uncompahgre, and Gunnison (GMUG) National Forests and vicinity, Colorado Multi-chapter report combining geologic, geochemical, geophysical, and mining activity data. Downloadable data for coal resource information only.
Hydrogeochemical investigations of historic mining districts, central western slope of Colorado, including influence on surface-water quality Geochemical analysis of mine dumps, mill tailings, mine drainage, and surface waters indicate contamination from these historic mines is generally less than that asserted or suggested by some geochemical models
