Abstract
The Jamestown, Gold Hill, and Magnolia mining districts of Boulder County, Colorado, provide one of the few classic examples of telluride mineralization in this country. These districts are parts of a broad, north-trending belt of telluride mineralization about 5 square miles in area located at the northeastern end of the Front Range mineral belt. The predominant country rocks are Precambrian granites, gneisses, and schists which are bounded on the east by Paleozoic and Mesozoic sediments upturned along the front of the range. The telluride veins represent one stage in a complex sequence of Early Tertiary ore types that show varying...
