云南省镇康县嗡空铅锌矿地质特征及成矿条件研究

摘要

Wengkong Pb-Zn Mine is located in " Sanjiang" belt south (South East of Luziyuan Pb-Zn ore).Its geological structure is complex and magmatic activity is strong.Metallogenic conditions are superior and prospects are broad.It is of important metallogenic area to look for lead-zinc-silver and other multi-metal ore.Through the analysis of regional geological background、metallogenic stratum and Lithology,it is believed that the lead-zinc deposits are located in the Cambrian sericite slate or in the marbleized crystalline limestone in the south-east wing of the rehabilitation anticline.On the shape,scale,occurrence and spatial distribution of the orebodies,we think that the ore-bodies are layered and lenticular.Its veined orebody is controlled by NW-trending fault zone.It is the formation of lead-zinc deposits in the area.Also,it is the result of the combination of stratum,tectonic and hidden rock mass.%镇康嗡空铅锌矿位于“三江”成矿带南段(芦子园铅锌矿床SE部),带内地质构造复杂,岩浆活动强烈,成矿条件优越,找矿前景广阔,是寻找铅锌银等多金属矿的重要成矿区.通过对区域地质背景和成矿地层、岩性分析,认为嗡空铅锌矿产于镇康复背斜南东翼寒武纪绢云泥质板岩及大理岩化结晶灰岩中;对矿体的形态、规模、产状及空间分布特征,认为矿体为受北西向断层破碎带控制的层状、透镜状、脉状矿体.研究区铅锌矿的形成,是受地层、构造、隐伏岩体三者联合作用的结果.
