| 摘 要： | 李坝金矿为近年发现的大型金矿。矿床产于秦岭造山带泥盆系浅变质细碎屑岩中，为一受岩性、断裂、蚀变带控制的蚀变岩型金矿。矿体严格受断裂破碎带控制。Ｆ１ 为主要导矿构造。矿床地质和地球化学研究表明，成矿物质主要来源于地层，成矿热液来源于大气降水、变质水和岩浆水，中川岩体为成矿提供了热动力条件

| Abstract: | Liba, one large gold deposit recently discovered, is hosted in Devonian epimetamorphic fine clastic rocks. It is controlled by lithology, altered fracturing zone and faults. The orebodies are strictly controlled by faults. F1 is an important ore-guided structure. The studies on geology of ore deposit and geochemistry indicate that the ore-forming materials are derived mainly from strata. The ore-forming fluid is a mixture of meteoric water, metamorphic water and magmatic water. Zhongchuan granite serves as the heating source for metallization. |
