据资料分析,我国铅锌矿床,绝大部分是属于层控矿床。但是,目前对层控的理解还不一致,对其成因分类的认识还不统一。本着“各抒己见”和“百家争鸣”的精神,就此提出一些看法,供大家研讨,敬请批评指正。 一、层控矿床的概念 近几年来,我国地质学界对层控矿床的研究十分重视,但对其含义迄今尚无统一说法。归纳起来,主要是两种观点: 1.系指受一定地层层位、岩性控制的沉积矿床,或矿化地层(矿源层),后受不同地质作用的改造、叠加或再造而形成的矿床,不包括典型的沉积矿床或产于层状侵入体内的矿床。
According to the data analysis, most of the lead-zinc deposits in China belong to the stratabound deposit. However, the current understanding of strata control is not the same, and their understanding of the causes of classification is not uniform. In the spirit of “expressing our opinions” and “contending for one hundred schools of thought,” we should offer some suggestions for our discussion and criticism. First, the concept of stratabound deposit In recent years, China’s geology community attaches great importance to the study of stratabound deposits, but so far there is no uniform meaning of its meaning. To sum up, there are mainly two kinds of views: 1. It refers to the deposit that is controlled by a certain stratigraphic layer, lithology, or mineralized strata (source bed) and then transformed, superimposed or reconstructed by different geological processes , Not including the typical sedimentary deposits or produced in bedded intrusion into the body of the deposit.
