凤县八卦庙金矿床构造控矿特征研究

Study on Characteristics of Structural Mineralization Control of Fengxiao

综合研究了八卦庙金矿床控矿构造的一般特征、力学性质、形成演化及其控矿特征。结果表明八卦庙金矿床的产出受脆-韧性剪切带、高角度叠瓦式逆冲断层及其派生构造双重控制。区内小褶皱控制着金矿体的形态及展布,后期NE向张剪断裂及张剪节理叠加其上,使金再次富集形成八卦庙金矿床工业富矿体。

The general characteristics,mechanical properties,formation and evolution of the mineralization control- ling structure of Baguamiao gold deposit and its mineralization controlling characteristics are comprehensively studied.The results indicate that the occurrence of Baguamiao gold deposit is dually controlled by its brittle-ductile shear zone,imbricate up thrust fault and its induced structure.The small folds in the zone control the shape and extension of gold orebody and the late supposition of NE transt...
