通过粤东北嵩溪银锑矿区的有机质特征及有机碳与成矿元素银、锑关系的研究 ,从有机地球化学角度对有机碳与成矿元素的共生组合关系以及有机质在成矿过程中的作用做了初步的探讨。有机显微组分中的大量藻质体及藻碎屑体指明了成矿早期的海相环境。在对矿区内黑色页岩系中的有机碳、硫、银、锑含量对比分析之后发现 ,有机碳与其三者存在着良好的正线性相关关系 ,有机质在银锑矿的形成过程中起到了重要的作用。研究工作的结果初步表明了有机质对银、锑等成矿元素的早期吸收、富集 ,从而导致矿源层的形成 ,体现出有机质在嵩溪银锑矿的形成过程中起到的重要作用。
Through the study on the relationship between the organic matter and organic carbon in the Songxi silver-antimony mining area in northeastern Guangdong and the relationship between the metallogenic elements silver and antimony, the symbiotic relationship between organic carbon and metallogenic elements and the role of organic matter in the metallogenic process from the perspective of organic geochemistry Made a preliminary discussion. The large amount of phycoplasts and algal debris in the organic micro-components indicate the marine environment in the early stages of mineralization. After comparing and analyzing the content of organic carbon, sulfur, silver and antimony in the black shale in the mining area, it is found that there is a good positive linear correlation between the organic carbon and the three, and the organic matter plays an important role in the formation of silver-antimony ore Role. The results of the preliminary work indicate that the organic matter initially absorbed and enriched the metallogenic elements such as silver and antimony, leading to the formation of the source layer, which reflected the important role of organic matter in the formation of the Songxi-Ag-Sb ore.
