Uranium in surface waters and sediments affected by historical mining in the Denver West 1:100,000 quadrangle, Colorado
Geochemical analysis of stream waters and sediments in mountainous areas immediately west of Denver, Colorado, to evaluate the concentration and distribution of uranium-bearing acid drainage originating from historical mines |
Info |
Geochemical results from stream-water and stream-sediment samples collected in Colorado and New Mexico
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. |

Geochronology Database for Central Colorado
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. |

Fluorine, fluorite, and fluorspar in central Colorado
Distribution of fluorine in specific age-lithologic categories, ranging from precambrian metamorphic rocks to modern soils. |
Info |
Geospatial database for regional environmental assessment of central Colorado
Study focusing on the effects of historical mining on Forest Service lands in this area. |

Reported historic asbestos mines, historic asbestos prospects, and other natural occurrences of asbestos in the conterminous United States
Site-by-site information on 876 natural occurrences of asbestos reported within the conterminous US. Includes location, mineralogy, geology, and relevant literature for each asbestos site. Data are provided in Microsoft Excel, shapefile, and CSV formats. |

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. |
