Mineralized Faults and Contacts in the Search for Gold

Bodie, California, in its heyday, was once rumored to be one of the roughest and most lawless towns in the American West.
It also happens sometimes that glaciers will bury valuable placer deposits. This occurs when the glacier goes over the top of an existing placer deposit.
Q: Is there a correlation between fault zones and mineralization of economic metals?
There are both hard rock and beach sand types of titanium deposits, but the hard rock deposits need to be at least 10 percent titanium while the beach sands often are economic with only two or three percent titanium.
The other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly foam.
The Wyoming State Geological Survey announced ten new geologic maps have been completed and are now available.
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
