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 |

Shapefiles to accompany Colorado Mineral Belt revisited
Based on detailed information on the location of the Tertiary intrusions and mineral deposits, and on the control provided by the Proterozoic structures, all superimposed using GIS, a new outline of the Colorado Mineral Belt is proposed. Older representations are included for comparison. Data are provided in shapefile format. |
