有机质与金属矿床的关系问题,是七十年代以来国内外地质工作者所重视的研究课题之一。不少学者对这个问题作过研究,并认为某些金属矿床的形成,常与有机质参与有密切关系。我国著名的万山型层控汞矿床,在物质组份上,常以富含有机质为特色。同时,在赋存汞矿床的中、下寒武统地层中,汞丰度与有机质含量亦有密切关系。本文主要通过对万山型层控汞矿床及其所赋存地层中的有机质与汞迁移、富集关系的初步研究,探讨有机质在层控汞矿床成因中的作用。
The relationship between organic matter and metal deposits is one of the research topics that geologists at home and abroad attach importance to since the 1970s. Many scholars have studied this issue and believe that the formation of certain metallogenic deposits is often closely related to the participation of organic matter. Wanshan-type stratabound mercury deposit in our country is characterized by rich organic matter in the material components. At the same time, in the middle and lower Cambrian strata in which the mercury deposits are deposited, the abundance of mercury also has a close relationship with the organic matter content. This paper mainly studies the relationship between organic matter and mercury migration and accumulation in Wanshan stratabound mercury deposit and its strata, and discusses the role of organic matter in the genesis of stratabound mercury deposit.
