Distribution of Hydrothermal Alteration associated with High and Low Sulfidation Deposits
Distribution of Hydrothermal Alteration associated with High and Low Sulfidation Deposits. High Sulfidation Epithermal Gold Deposits form in geothermal systems where hot acidic hydrothermal fluid directly from the intrusion, remains undiluted by ground water. Low Sulfidation Deposits on the other hand, from a geothermal system in which the magmatic fluid is cooled and diluted by groundwater and the pH is neutralized at depth. White, N.
