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.

Geologic units, structural features, and aeromagnetic anomaly map of the area

Multi-chapter report combining geologic, geochemical, geophysical, and mining activity data. Downloadable data for coal resource information only.

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

Ground- and surface-water samples were collected in order to characterize the local ground-water flow system, determine metal concentrations in local ground water, and understand factors controlling the discharge of metal-rich waters from the mine.

New age determinations with descriptions of sample locations and analytical details.

Data from a study intended to explore how well the chemical analysis of water and sediment in an area reflects that of the rock from which the sediments are eroded and through which the water flows.

A study conducted collected 57 surface rock samples from nine types of intrusive rock to reexamine the chemistry and metallic content of the major rock units of the Iron Hill complex

Compilation of isotopic and fission track age determinations, some previously published. Data for the tephrochronology of Pleistocene volcanic ash, carbon-14, Pb-alpha, common-lead, and U-Pb determinations on uranium ore minerals are not included.

Distribution of fluorine in specific age-lithologic categories, ranging from precambrian metamorphic rocks to modern soils.

Periodic sampling of water during the spring of 2010 was carried out to understand the range and timing of variation in pH and metal concentration, and help evaluate variation in water quality during spring runoff.

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

Detailed descriptions of more than 200 mineral districts, mines, and mineral occurrences (deposits, prospects, and showings) within the United States that are reported to contain substantial enrichment of rare earth elements.

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.
