研究环太平洋带中一新生代的金矿成因可以阐明金—银矿化和其他金矿建造的关系。环太平洋带的西部山西向东金矿床的形成,由侏罗纪—晚上新世逐渐变新。最老的是金—石英建造矿床(晚侏罗世—早白垩世),它们赋存于厚大的侏罗—三叠系陆源碎屑岩地层中,矿床具有下列主要特征:石英是矿石的主要成分,金呈游离状态,矿石矿物成分简单,矿体形态呈脉状和细脉状。
The study of the genesis of a Cenozoic gold deposit in the Pacific Rim can illustrate the relationship between gold-silver mineralization and the construction of other gold deposits. The formation of the Xiangdongdong gold deposit in the western Pacific Rim has gradually changed from the Jurassic to the Late Pleistocene. The oldest is the gold-quartz deposit (Late Jurassic-Early Cretaceous), which occurs in thick Jurassic-Triassic terrigenous clastic formations with the following main features: quartz is ore The main components, gold was free state, simple mineral composition of ore, ore body morphology was veins and veinlets.
