摘要
围山城金银矿带位于桐柏一大别山金银成矿带北亚带。矿带内各金银矿床的成因类型为构造—蚀变岩型金银矿床,新元古代歪头山岩组既是矿带内的赋矿地层也是重要的矿源层,矿体严格受构造控制,围岩蚀变与矿化关系密切。本文从围山城矿带内地层、岩石、构造、围岩蚀变类型等方面,对矿带内金银矿床的成矿条件、成矿控制因素等进行了综合分析,探讨了构造变形过程与成矿作用的关系,并对找矿标志进行了总结。
The gold-silver deposits in the Weishancheng Mineralization Belt are strictly controlled by the specified strata,characterized by thermal alteration.The ore bodies are subject to the structural conditions.The producing formations have variable alteration under thermal fluid indicating there is a close relationship between wall rock alteration and mineralization.This paper raises a dowsing index via the strata,rocks,structure and wall rock alteration.
