摘要:
江西瑞昌上湾铜多金属矿床是在九瑞矿集区界首—大桥背斜核部首次发现的中型矿床规模以上的斑岩—矽卡岩型铜多金属矿床。文章通过分析上湾铜多金属矿的地质特征,总结该矿床的找矿标志。结果表明,该矿床的矿体主要呈浸染状、细(网)脉浸染状、条带状产出于花岗闪长斑岩及其与奥陶系碳酸盐岩接触带的矽卡岩中。花岗闪长斑岩为矽卡岩型矿体的成矿母岩,具富碱高钾及壳幔混合的特征,认为背斜核部及奥陶系与志留系之间薄弱面是此类矿床重要的找矿标志。
Abstract:
The Shangwan copper polymetallic ore deposit is a medium-sized porphyry-skarn copper polymetallic deposit in the city of Ruichang, Jiangxi Province, which was firstly discovered in the core of the Jieshou-Daqiao anticline developed in the Jiurui ore concentration district. This paper summarized the prospecting criteria based on analysis of the geologic features of the Shangwan copper polymetallic deposit. The result shows that the orebodies of the deposit occur as disseminated, fine vein disseminated and banded ores in the contact zones between granodiorite-porphyry and Ordovician carbonatic rock. Granodiorite-porphyry was the parent rock for the skarn-type deposit, with the characteristics of high-alkali and high-K and crust-mantle mixing. It is concluded that the core of anticline and contact zones between Ordovician and Silurian are the prospecting targets for the deposits of this kind.
