Limestone Gold Relationship - Geology and Ore Deposits ...

17/02/2014 · Gold is also found in volcanogenic massive sulfide deposits. The "association" of gold with limestone can be a matter of gold in solution, venting through fractures in limestone. Since limestone is "basic" in a chemical sense, sulfide solutions that are acidic will under certain conditions dissolve limestone and form massive sulfide deposits that may include gold.
