四川大宝山铜矿区矿床地质特征及找矿方向

Geology and exploration prospects of the Dabaoshan copper deposit in Pengzhou,Sichuan

层控矿床属火山-沉积变质成因;含铜石英脉型矿床为热液充填成因。根据成矿控制因素和找矿标志,对大宝山地区的成矿远景进行了划分,指出了进一步的找矿方向。

Two types of copper deposits are recognized in the Dabaoshan copper mining district in Pengzhou, Sichuan： stratabound and Cu-bearing quartz vein deposits. The stratabound copper deposit should have a volcanic and sedimentary-metamorphic origin while the Cu-bearing quartz vein copper deposit is of hydrothermal filling origin. The delineation of the exploration prospects has been made on the basis of controlling factors and prospecting criteria.
