摘　　要：处于西伯利亚板块南缘大兴安岭北部的巴林地区，在1：5万水系沉积物测量中发现其中一处Pb、Zn多金属异常，伴生M0、Ag、Cu等。经土壤测量验证，异常再现良好；经槽探揭露，发现铅、锌矿化带。矿化主要分布在早白垩世花岗闪长岩、中粗粒黑云二长花岗岩内外接触带，赋存于北东向及北西向断裂蚀变破碎带中，蚀变有硅化、钾化、绿泥石化等，推测深部有隐伏热液充填型铅锌多金属矿床，找矿前景乐观。According to the measurement of 1：50000 stream sediment in the Balin area, one place at the north of Paleozoic accretion-type orogens of Daxing＇ anling Mountains which located in the southern fringe of the Siberia plate, with Pb, Zn poly-metallic anomaly dominantly being associated with Mo, Ag, Cu, anomalies has been detected. The anomalies are represented well, and the Pb, Zn mineralized zone have been discovered through trench prospecting. Mineralization stretched across the contact between granodiorite and medium-coarse grained biotite adamellite in the Early Cretaceous and occurred in fractured alteration belt which is trended with north- east or north-west. The alternation types have included silication, potassium-feldsparization, chloritization, epidotization and beresitization. The genesis of hydrothermal-filling and deep-concealed Pb, Zn poly-metallic deposit has been concluded as with optimistic perspective.
