It is commonly associated with epithermal precious metal deposits where alteration is associated with boiling fluids and condensation of volatilerich vapors to form extremely acidic solutions. Silicification refers specifically to the formation of new quartz or amorphous silica minerals in a rock during alteration and is usually a by-product of isochemical hydrolysis reactions where Si is locally derived. These deposits form a mineralized package that is of economic interest to the miner.
