摘　　要：白石崖铁多金属矿田位于东昆仑东段,距青海省都兰县城西20多公里,矿田内的矿床大多赋存于下石炭统大干沟组碳酸盐岩与中酸性火山岩或酸性侵入体接触带矽卡岩带中。白石崖地区成矿特征显示,本区具有寻找铁铜铅锌钨锡的地质条件。以M20矿床为突破口,采用磁法、EH4连续电导率剖面测量及钻探查证等技术,开展了以铁多金属为主的找矿工作,发现并探明了一批有一定储量的多金属矿体,并于深部岩体附近发现钨矿体,实现了近年来白石崖地区找矿的重大突破。The Baishiya iron-multimetallic ore field is located at the East Kunlun Mountains,about 20km west to Dulan County of Qinghai Province. Most deposits of this ore field occur in the contact belt among carbonate of the Dagangou Group, intermediate-felsic volcanic rocks and acid introsions.The mineralization features show that this area has favorable geological conditions for further prospecting polymetallic deposits of Fe, Cu, Pb, Zb, Sn, W and so forth.Starting from the M20 deposit, magnetic survey, EH4 electrical conductivity measurement and exploration drilling were conducted,leading to discovely of an amount of polymetallic ore bodies with some reserves in this area.A tungsten body was also found nearby a deep rock mass.These results imply an im- portant breakthrough of ore-search efforts in recent years in the Daishiya area.
