State Specific Information on Gold & Other Minerals

Here is some state specific information to get you started on your search for gold and other valuable minerals. A lot of the basic information is drawn from Principal Gold-Producing Districts of the United States by A. H. Koschmann and M. H. Bergendahl, 1968 USGS Professional Paper 610 at http://www.dggs.alaska.gov/webpubs/usgs/p/text/p0610.PDF and then updated where possible.

Most of the principal gold-producing districts are in the mountainous areas of the United States, where folding, faulting, and igneous intrusions have deformed the rocks. In contrast, many large base-metal deposits are found in the large relatively un-deformed areas of the Central and Eastern States, but gold is not even a byproduct of these ores. Large parts of the Western States, such as the Colorado Plateau, the Columbia Plateau, and much of Wyoming, have not been subjected to violent tectonic forces and consequently contain very few gold deposits. Most of the gold deposits in the United States are associated with and are perhaps genetically related to small batholiths, stocks, and satellitic intrusive bodies of quartz monzonitic composition that range in age from Jurassic to Tertiary. Some deposits, such as those in the Southeastern States, may be genetically related to granitic bodies that were intruded at the close of Paleozoic time, and a few deposits, as at Jerome, Ariz., are Precambrian in age.

Australia

Nobody knows what the production figures are but there is little doubt hundreds of thousands of ounces of gold have been found in Australia by prospectors with metal detectors in the last 40 years. Gold in Australia
