摘要
维宝铅锌矿是2002-2003年中国地质调查局青藏高原东缘国土资源综合调查项目子题《新疆昆仑山东段布喀达坂峰—依吞布拉克1∶20万区域化探》项目的主要成果,经过几年的普查证实矿床具中型以上规模。Cu、Pb、Zn、A g区化最高值依次为93.1×10-6、291.9×1-0 6、359.7×1-0 6、1 673×10-6。矿床位于蓟县系狼牙山组大理岩夹钙质粉砂岩段的矽卡岩带中,矿化蚀变带宽约150 m,长度大于3 000 m,矿体延深大于400 m。地表共有矿体21条,形态为似层状和透镜状,属层控矽卡岩型铅锌矿床。矿石类型有条带状和浸染状。主要金属矿物为方铅矿、闪锌石和黄铜矿。累计求得Pb＋Zn资源量为61.43万t。
Weibao lead-zinc deposit is main achievement of an investigation in east part of Kunlun mountain in Xinjiang,which is a sub-project of land and resources comprehensive investigation projects,carried out in Qinghai-Tibet Plateau by China Geological Survey in 2002-2003.This deposit has been proved to be larger than a medium one on a scale by general survey in several years.The content of Cu,Pb,Zn,Ag can reach to 93.1×10-6,291.9×10-6,359.7×10-6,1673×10-6.Ore zone of this deposit is 150m wide,more than 3 000 m in length and 400m in depth.On earth＇s surface,there occur 21 lenticular,bedded ore bodies,with lead glance,zinc blende and chaleopyrite as main metal minerals in them.Reserves of lead and zinc amount to 614.3 thousand tons;copper and sliver as the associated minerals amount to 17 thousand tons and 420 tons.
