云南澜沧老厂银铅锌铜多金属矿床构造特点及成因认识

Tectonic Features and Ore Genesis of Laochang Silver-lead-zinc-copper Polymetallic Ore in Lancang of Yunnan

澜沧老厂矿床位于“三江”成矿带南段的昌宁-孟连Pb、Zn、Ag、Cu、S、Hg多金属成矿带矿带内,区内构造复杂,岩浆活动强烈。对于老厂矿床找矿研究近年来引起众多业内学者重视,但对于该矿床的成因认识,分歧较大,在前人已有研究基础上,从矿床构造特点、成岩成矿时代、成矿物质来源、矿床成因等方面开展了综合研究和总结,以期为矿床下步地质找探矿及科研工作提供参考。

Laochang deposit of Lancang located in metallogenic belt of Changning-Menglian Pb,Zn,Ag,Cu,S,Hg polymetallic ore in"Sanjiang"metallogenic belt,the construction of the area is complex,the magmatic activity is strong.Mineral exploration of Laochang deposit has attracted attention of many scholars in the industry,but there are considerable differences about the cause of deposit formation.therefore the comprehensive research and summarization was developed from the aspects of deposit structural characteristics,ages of petrogenetic and metallogenic,ore-forming material source,cause of deposit formation and the so on on the basis of previous research,in order to supply reference to the next geological prospecting and scientific research work.
