摘　　要：在1∶5万水系沉积物测量的基础上,分析了大草湖地区钼钒磷金铜等元素的地球化学特征。通过对成矿元素的分布特征及相关性分析、因子分析,认为寻钼钒磷金铜矿床潜力较大;根据异常特征及成矿地质条件,在早寒武世西大山组和晚泥盆世破城子组地层背景下,寻找与早寒武世西大山组地层相关的钼钒磷层控沉积型和与晚泥盆世破城子组相关火山岩型金铜矿床潜力较大,进而划分出3个成矿远景区,即乔龙库图克南钼、磷、钒、银、锌、铁、铜成矿远景区、大草湖南钼、磷、铅成矿远景区、铜矿山金、铜、钨多金属成矿远景区。On the basis of stream sediment measurements with the scale of 1∶50000,geochemical characteristics of molybdenum,vanadium,phosphorus,gold and copper in Dacaohu area have been analyzed.Through analysis on distribution characteristics and correlation of metallogenic elements and factor analysis,it is considered that the potential of molybdenum-seeking vanadium-phosphorus-gold-copper deposit is great.According to the anomalous characteristics and metallogenic geological conditions,under the stratigraphic background of Xidashan formation of early Cambrian and Pochengzi formation of late Devonian,It has great potential to search for molybdenum-vanadium-phosphorus stratabound deposits related to Xidashan formation of the early Cambrian and volcanic rock-type gold-copper deposits related to Pochengzi formation of the late Devonian.Three metallogenic prospective areas have been divided,they are Qiaolong Kutuknan molybdenum,phosphorus,vanadium,silver,zinc,iron and copper metallogenic prospecting area,Dacao Hunan molybdenum,phosphorus,lead metallogenic prospecting area,and gold,copper,tungsten polymetallic metallogenic prospecting area in cooper mine.
