| 摘 要： | 枣子沟金矿为近年发现的大型金矿。矿床产于秦岭造山带三叠系浅变质细碎屑岩中,为一受岩脉、断裂、蚀变带控制的构造蚀变岩型金矿床,矿体严格受断裂破碎带控制。矿床地质和地球化学研究表明,成矿物质主要来源于岩浆期后中—低温热液。岩浆活动为成矿提供热动力和物质来源。

| Abstract: | Zaozigou gold deposit is discovered recently,but its resource reserve is up to large scale.It is hosted in Triassic epimetamorphic fine clastic rocks,controlled by dike,altered fracturing zone and faults.The orebodies are strictly controlled by faults.The studies on geology of deposit and geochemistry indicate that the ore-forming materials are derived mainly from post-magmatic mineral fluid.Magma serves as the heating source and materials for metallization. |
