凤县八卦庙金矿床构造控矿特征研究

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。

Study on Characteristics of Structural Mineralization Control of Fengxiao

The general characteristics, mechanical properties, formation and evolution of the mineralization controlling 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 transtensional faults and joints has re-enriched the gold to finally form commercial rich orebodies in Baguamiao gold deposit.
