摘要
云南西畴县嘎机铅锌矿处于都龙复式花岗岩基向北侧伏的地带,铅锌矿体主要呈似层状赋存于构造破碎带中,该铅锌矿具有层控-岩浆期后热液矿床的特征。中寒武统田蓬组(∈2t)碳酸盐岩-碎屑岩互层组合、背斜构造、隐伏花岗岩体脊状凸出部位、矽卡岩化围岩蚀变和物、化探异常等是本区的主要找矿标志。
Gaji Pb-Zn deposit in Xichou,Yunnan is in the northward plunge area of Dulong composite granite batholith.The Pb-Zn orebody is mainly stratoid in the structure fracture zone.It is a stratabound deposit.The main prospecting criteria are Middle Cambrian Tianpeng Formation(∈2t)carbonate rock-clastic rock interbedding assemblage,anticline structure,crest protruding part of buried granite body,skarnization alteration of wall rock and geochemical-geophysical exploration anomalies,etc.
