Is Gold Found In Limestone? Ceramics

2021-6-16  HOWEVER gold does not occur ‘naturally’ in limestone. The gold is introduced LATER by migrating hydrothermal fluids, which DEPOSIT gold (and some other elements) in suitable host rocks and limestone, particularly ‘dirty’ (with silt, mud and other materials) limestone is a very suitable host rock.

Limestone Gold Relationship Geology and Ore

2014-2-17  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.

geology How does quartz form in calcite veins?

2016-12-31  Calcite and quartz are both common, almost ubiquitous in limestone veins. Obviously, the calcite is re-precipitated limestone. The groundwater chemistry undergoes cycles according to recharge characteristics, temperature, pressure and partial pressure of CO2, so sometimes it dissolves and re-precipitates the same carbonate
