摘　　要：蒙西斑岩铜矿是东准噶尔琼河坝地区新发现的低品位大中型铜矿,为早泥盆世与花岗斑岩和闪长玢岩有关的斑岩铜矿.矿区地质、地球化学和地球物理调查结果显示,矿床的矿(化)体具向NW向侧伏的特征.物探成果显示矿区北侧存在一处规模较大的异常,该异常成矿地质条件有利,是找矿工作的有利地段.Mengxi porphyry copper deposit located in the Qiongheba area,eastern Junggar was a new discovered low-grade middle-big porphyry copper deposit associated with granitic and dioritic porphyries emplaced at early Devonian.New geological,geochemical and geophysical datas indicate that the ore-bodies in the Mengxi copper deposit were pitched northwestwards.The geochemical and geophysical datas also show that there was a big abnormity at the north area of district.It was suggested that the big abnormity was most possible a good potential target for buried copper deposit.
