OF-12-02 Colorado Map of Potential Evaporite Dissolution and Evaporite Karst Subsidence HazardsE-mail this product to a friend
Large areas of Colorado are underlain by Mesozoic and/or Paleozoic evaporite deposits. The purpose of the CGS Colorado Map of Potential Evaporite Dissolution and Evaporite Karst Subsidence Hazards is to describe the geologic conditions where near-surface evaporite rocks occur in Colorado and the general description and hazard potential of ground subsidence that can occur from rock dissolution in evaporite terrain. This publication includes a statewide map in PDF format at a plate size of 54″ by 42″ size (1:500,000 scale), an illustrated 28-page map discussion report (PDF), and GIS digital data prepared as ESRI shapefiles.
The data includes those areas of Colorado underlain by near-surface evaporite bedrock and point locations of sinkholes and subsidence features where they have been discerned. The CGS Critical Geologic Hazards Program is funded by the Colorado Department of Natural Resources Severance Tax Operational Funds — severance taxes paid on the production of natural gas, oil, coal, and metals in Colorado.
