摘　　要：东乡火山岩盆地近年来不断发现金银铜多金属矿床(点)。根据盆地内典型矿床地质、地球化学特征,结合1∶20万区域地球化学资料和1∶5万土壤测量圈出的地球化学异常地段,估算了盆地内可富集的金属资源量,并圈出了有远景的找矿靶区。Au, Ag, Cu polymetallie deposits （ ore spots） were discovered in succession in Dongxiang volcanic basin. According to geo- logical and geochemical characteristics of typical ore deposits in the basin in combination with 1 ： 200 000 regional geochemical data and geochemical anomaly sectors delineated by 1： 50 000 soil survey, the authors estimated the quantity of concentrated metallic re- sources in the basin and delineated promising ore-prospecting targets.

关 键 词：火山岩盆地 铜多金属矿 地球化学异常 金属资源量 找矿靶区
