早子沟金矿矿体及地球化学特征

早子沟金矿位于秦岭造山带西段夏河—合作断裂带上，地质构造复杂，成矿条件优越。矿体赋存于三叠纪浅变质细碎屑岩和印支晚期的中性岩脉中，矿床成因类型为岩浆期后中—低温热液（交代）构造蚀变岩型金矿床。矿体分布受断裂构造控制明显，为多期热液叠加成矿，断裂产状变化部位、不同断裂交汇处、断裂构造局部引张地段，往往是金的矿化富集部位。本文对矿区矿体及地球化学特征进行了总结，探讨该矿床地质—地球化学勘查模式，可作为在该区域寻找类似矿床的参考。

Ore-Body Geochemical Features of Zaozigou Gold Deposit

Zaozigou gold mine is located in Xiahe-Hezuo fault of Qinling orogenic belt with complex geological structures and mineralization favorable conditions. It is a post-magmatic structural altered rock type gold deposit related to low and moderate temperature hydrothermal activities. Ore bodies exist in Triassic low-grade metamorphic clastic rocks and late Indosinian intermediate dykes, controlled by faults. The paper summarized orebodies and their geochemical features, and put forward the geological-geochemical exploration model which may be a guide for prospecting the similar deposit in the research region.
