摘要
对大村铜矿区综合研究,认为塔包谷么向斜是主要的控矿构造,上白垩统江底河组大村段为矿区的含矿层。而且页岩层和砂岩层的矿化明显优于砾岩层,大村铜矿矿化明显受构造、地层和岩性,以及碎屑粒度的制约。
According Tabaogumuo synchne is the to the comprehensive study of Dacun Cu Orefield, we believe that the main ore - controlling structure and the ore - beating bed is the Dacun Member of Upper Cretaceous Jiangdihe Formation in the orefield. And the metallogenesis of shale and sandstone is clear better than that of conglomerate. Metallogenesis of Dacun Cu deposit is controlled evidently by the structure, strata, lithological character and grain size of clastics.
