    Geology and Geochemistry of Epithermal Systems presents a synthesis of the current under­ standing of the processes responsible for the concentration of metals (especially gold and silver) in near-surface environments, provides an overview of the systematics of the most important approaches to the study of epithermal ores and processes, and summarizes the geology of both sediment-hosted and volcanic-hosted epithermal Low Sulphidation Epithermal Gold Deposits,Although they are a product of the same igneous system, low sulfidation epithermals gold deposits are very different from high sulfidation. In low sulfidation the main control for Gold deposition, is fluid boiling caused by a drop in the confining pressures the fluid approaches the surface.

    Oct 17, 2019· Epithermal gold deposits are among the richest gold deposits in the world with some bonanza grade ore shoots containing more than 1000 g/t gold, or in other words, a kilogram of gold for every tonne of rock mined. Unfortunately, the tonnage of ore in epithermal veins is typically small compared with other types of lower grade gold deposits. Gold mineralisation within epithermal Epithermal Gold for Explorationists AIG Journal,Note the term epithermal is not incorporated in the names of the deeper arc low sulphidation styles (quartz- sulphide gold ± copper, polymetallic gold-silver, and carbonate-base metal gold), which in some instances form at greater depths than would be expected for epithermal gold deposits.
