Physico Chemical Conditions of Their Formatior and Altered Zones of Gold Deposits within Volcanic Provinces Four Dimension Records of Interactive Process between Ore Forming Hydrothermal Fluid System and Ore Controlling Environment
|
Abstract:
This paper mainly discusses the formation conditions and altered zones of gold deposits in areas of volcanic rocks,subvolcanic rocks and hypabyssal intrusive rocks.The author divides the ore forming system into the ore forming hydrothermal fluid system and the ore controlling environment.The hydrothermal fluid system is further divided into the near surface and high level emplacement hydrothermal fluid systems.The author analyzes in an all sided way the geological environments and temporal spatial distribution of altered mineral assemblages of various gold deposits associated with the two kinds of hydrothermal fluid systems as well as the geological and physico chemical conditions of their formation.
