TECTONIC-LITHOFACIES FEATURES OF GOLD DEPOSIT OF METAMORPHIC ROCK TYPE IN EASTERN SHANDONG AND ITS ORE-CONTROLLING

摘要: 本文简述了胶东变质岩型金矿的构造-岩相特征。通过对构造体系及其复合成分的控矿和成矿作用,断裂性质和规模控制矿化类型和蚀变特征,构造-岩相类型控制矿化分带和矿体组合特征等方面的综合研究,分析了构造-岩相型式的控岩控矿作用,并对胶东变质岩型金矿构造-岩相成矿系列和成矿模式进行了探讨。

Abstract: The tectonic-lithofacies features of gold deposit of metamorphic rock type in the Eastern Shandong are described in this paper.A comprehensive study of the control of ore deposits by tectonic systems and their compounding,the control of mineralization type and alteration by faulst size and their mechanical properties,the control of mineralization zoning and orebody assemblage by tectonic-lithofacies patterns is made.As a result the control of ore and rock by tectonic-lithofacies patterns is analyzed.The tectonic-lithofacies metallogenic series of the gold deposit of metamorphic rock-types in the Eastern Shandong as well as a model of its formation is also discussed.
