| 摘 要： | 杨家寨金多金属矿位于西藏—三江造山系,兰坪—普洱双向弧后陆内盆地与绿春陆缘弧带结合部,矿体近矿围岩主要为下二叠统高井朝组安山质凝灰岩及安山岩,少部分为石英斑岩,矿体就位于与莫马洛断层（F4）成锐角度相交的次级构造、层间破碎带及层间剥离—滑脱构造带.成矿作用共分三个阶段：早二叠世晚期——矿源岩（层）形成阶段,燕山早期——矿床形成阶段;燕山晚期——矿床定位阶段.矿床类型为浅成低温热液构造—蚀变岩型多金属矿床. |
| 关 键 词： | 构造—蚀变岩型 成矿模式 金多金属矿 云南绿春杨家寨 |

| Abstract: | Yangjiazhai Au multimetallic deposit is in the conjunction zone of Xizang-Sanjiang orogenic sys- tem, Lanping-Puer bilateral back-arc inland basin and Luchun epicontinental arc zone. The wall rock close to ore body is mainly lower P Gaojingchao Formation andesitic tuff and andesite and a little quartz porphyry. The ore body is in the secondary structure intersecting in acute angle with Momaluo fault （F4 ）, interbed fracture zone and inter- bed desquamation-gliding structure zone. The metallogenesis can be divided into 3 stages： late period of early P ore source bed formation stage; early Yanshanian ore deposit formation stage and late Yanshanian ore deposit em- placement stage. The type of ore deposit belongs to the low T epithermal structure-alteration type muhimetallic de- posit. |
