川滇黔地区MVT铅锌矿床成矿地质特征及找矿方向

Metallogenic geological characteristics and prospecting direction of MVT Pb Zn deposit in Sichuan Yunnan Guizhou area

川滇黔成矿带是我国19个重要成矿带之一,已发现会泽、天宝山等一大批(超)大、中、小型MVT型铅锌矿床。前人对该成矿带找矿方向研究较少,本文认为川滇黔地区断裂发育区域或断裂交汇处,震旦系灯影组结晶白云岩、硅质白云岩,下寒武统麦地坪组白云岩和石炭系摆佐组灰岩、白云岩、白云质灰岩中是寻找MVT铅锌矿床最为有利的地区。

The Sichuan Yunnan Guizhou metallogenic belt is one of the 19 important metallogenic belts in China.A large number of(super)-large,medium and small-sized MVT type lead-zinc deposits,such as Huize and Tianbaoshan,have been found.There are few previous studies on the prospecting direction of this metallogenic belt.This paper considers that the most favorable area for the exploration of MVT lead-zinc deposit is the fracture development area or fracture intersection in Sichuan Yunnan Guizhou area,crystalline dolomite and siliceous dolomite in Dengying Formation of Sinian system,dolomite in madiping formation of Lower Cambrian and limestone,dolomite and dolomite limestone in baizuo formation of Carboniferous system.
