我国南方泥盆纪碳酸盐地层内,赋存着许多具有工业意义的铅锌、黄铁矿和多金属矿床。凡口铅锌矿床就是其中比较有代表性者。由于这些矿床经济意义巨大,分布较有规律,所以近年来地质学家们对它们颇感兴趣。关于它们的成因,更是一个热门的论题。 鉴于矿石是一种特殊的岩石,所以欲查明矿石成因,必须对其所赋存的岩石的成因加以研讨。G·C·Amstutz(1964)曾阐述道:“每一种岩石都有其天生的一份矿床,这份矿床与岩石同时形成并且是同源的”。这说明矿床成因与岩石成因是密不可分的。
Within the Devonian carbonate strata in southern China, many industrial lead-zinc, pyrite and polymetallic deposits occur. Fankou lead-zinc deposit is one of the more representative. Because of their economic significance and their regular distribution, these geologists are very much interested in them in recent years. On the causes of them, but also a hot topic. In view of ore is a special kind of rock, so to find out the cause of ore, we must study the genesis of the rock that it contains. G.C. Amstutz (1964) stated: “Each rock has its own natural deposit, which is formed simultaneously with the rock and is homologous.” This shows that the cause of the deposit and rock formation are inextricably linked.
