摘要
金厂峪地区的构造非常复杂，与金矿的成矿作用关系密切。太古代末形成的韧性剪切带和金矿无直接成因联系，但为后期脆一韧性剪切带的叠加提供条件。金厂峪金矿是中生代脆一韧性变形带和脆性断裂形成过程中产生的，严格受北北东向脆一韧性剪切带和脆性断裂控制，在两个阶段矿化叠加部位，金矿进一步富集，构成金厂峪型金矿。
The tectonics of Jin-Chang-Yu area is very complicated and closely related to the gold mineralization of this region. The ductile shear zone (DSZ) which was formed in late period of Archaean era has no direct relation with the genesis of gold deposit, but it offered conditions for the superimposition of late brittle-ductile Shear zones. Jin-Chang-Yu gold occurred in the course of the formation of brittle-ductile shear zone(B-DSZ) and the brittle fault(BF)in Mesozoic era. which was strictly controlled by these NNE B-DSZ and BF. Gold was further enriched in the surperimposed parts of the two Periods of mineralization, which constitute Jin-Chang-Yu type of gold deposit.
