From the Introduction:
Gunnison County is located in central/southwestern Colorado in an area of diverse geology. Precambrian through Tertiary rocks occur throughout the county and have undergone different stages of development. Most of the geologic provinces in the county contain economically important deposits of minerals or mineral fuels. Discussed are fourteen districts having base- and precious-metals resources and twelve districts having energy, alloy metal, and industrial mineral areas. Included in the latter category is the famous Yule Marble. Also discussed are four areas having geothermal resources, two having coal resources, and one having petroleum resources.
