现在,人们越来越清楚,复成矿床的分布是十分广泛的。它是由不同成因的各种矿化作用所生成的。描述矿区中各种矿化作用间具体相互关系的资料,至今还是很有限的。因此,下面我们介绍一种有价值的资料,这是笔者在详细研究一个矿床时搜集到的。该矿体中出现了两个矿物组合,其生成时代、矿物组成和含金量均不相同,显然这是与含矿溶液的来源不同有关。矿床赋存在早加里东期(O_1——C_3)花岗质岩基中,它侵入到晚古生代的碳酸盐—陆源地层中。该地层的南面以地堑为界,地堑被早——中奥陶纪火山成因的及红色
Now, people are more and more clear, the distribution of complex deposits is very wide. It is generated by various mineralization of different causes. Information describing the specific interrelationships among various mineralizations in the mining area is still limited. Therefore, below we introduce a valuable information, which I collected in a detailed study of a deposit. There are two mineral assemblages in this orebody. The times of formation, mineral composition and gold content are different. Obviously, this is related to the different sources of ore-bearing solution. The ore deposit is hosted in the Early Caledonian (O_1 - C_3) granitic basement and intrudes into the Late Paleozoic carbonate - terrigenous strata. The south of the strata is graben-cut, and the graben is dominated by early-middle Ordovician volcanoes and red
