MS-51 Interpretive Geothermal Gradient Map of Colorado

The Interpretive Geothermal Gradient Map of Colorado depicts the change in temperature with depth below the Earth’s Surface throughout Colorado. Geothermal gradient values quantify the depth-temperature relationship used in evaluating geothermal resource potential. Geothermal gradient data are one of several types of data that indicate the quality of geothermal resources in an area. Other data types that are useful in assessing geothermal resources include geothermal heat flow, geothermometry, geophysical data (electrical, magnetic, magnetotelluric, gravity, remote sensing), and shallow-depth ground temperature measurements. This publication compiles geothermal gradient data from several sources. These include past CGS geothermal publications, national and global heat flow databases, and Colorado oil, gas and CO2 well data. Despite the abundant data used to create this map, the data points are distributed irregularly throughout the state. Some map areas lack significant data control and, therefore, are for geothermal resource exploration, especially when used in conjunction with other types of geological, geophysical, and hydrogeological data. This CD contains three map plates, two report documents, a geothermal gradient database, and the native Geographic Information System (GIS) geospatial data files through which, the interpretive geothermal gradient maps and projected temperature-at-depth maps were created.
