王家窝铜多金属矿矿体地质特征研究

Study on Geological Characteristics of Ore Body of Copper Polymetallic Deposit in Wangjiawo

云南省王家窝矿产资源丰富,有石膏、硝土、硅石、花岗石、金、银、铁、铅、锌等矿产资源。景谷县王家窝铜多金属成矿带,为北北西走向,矿体赋存于断层破碎带中,直接围岩为中侏罗统花开左组(J2h)灰岩、下白垩景星组(K1j)长石石英砂岩岩层[1]。以铜、铅、锌为主攻矿种,采用地、物、化相结合的方法,快速大致查明了工作区成矿地质条件和蚀变矿化特征,地球物理、地球化学特征以及前期工作中已圈定的主矿体资源量前景。

Wangjiawo in Yunnan province has rich mineral resources,including gypsum,soil nitrate,silica,granite,gold,silver,iron,lead,zinc and other mineral resources.Jinggu County-Wangjiawo copper polymetallic metallogenic belt is NNW.The ore bodies occur in the fault zone,direct surrounding rock are Middle Jurassic huakaizuo（J2h）limestone,lower Cretaceous Jingxing group（K1j） feldspar quartz sandstone strata[1].Taking copper,lead and zinc as main minerals,combining ground,object and chemical methods,ore-forming geological conditions,alteration mineralization characteristics and geophysical and geochemical characteristics and the prospects for the quantity of the main ore resources has been delineated in previous work are quickly and roughly identified.
