胶东西北部金矿床成矿物理化学条件初探

METALLOGENIC PHYSICO-CHEMICAL CONDITIONS OF THE GOLLD DEPOSITS IN THE NORTHWEST REGION OF EASTERN SHANDONG

摘要:

探讨了金矿床形成的温度、压力、酸碱度、氧化还原电位、矿液成分及矿物包裹体氢、氧、碳同位素组成，成矿作用中物理化学条件的变化，含金石英脉金矿与蚀变岩型金矿成矿物理化学条件的差异。

Abstract:

In this paper the author discussed the plysicochemical conditions,such as temperature, pressure, pH,Eh,ore一fluid compositions and H,O,C compositions of fluid inclusions in mineralsand the ir ver iations in ore一for ming process of the gold deposi ts in eastern shandong.Thedifference of physico一chemical conditions between the quartzvein type and the aIteration type ofgold deposits is also discussed.
