从矿石和围岩可溶有机质的生物标志化合物、非烃的红外光谱学特征 ,以及有机包裹体的光学和谱学特征等方面论述了金牙金矿床的有机地球化学特征及其有机流体的成矿作用 ,查明了参与成矿的有机质主要来源于菌藻类等低等生物 ,流体有机质的成分、结构、成熟度等随成矿作用的进行而不断演化。在有机碳、金含量及藻类成矿作用模拟实验的分析基础上 ,认为流体有机质参与成矿的方式主要是活化萃取、还原沉淀 ,而干酪根则对金起富集作用。
In this paper, the organic geochemical characteristics of the gold-dental gold deposits and their organic fluid-forming properties are discussed from the biomarkers biomarkers of soluble organic matter in ores and surrounding rocks, infrared spectra of non-hydrocarbons, and the optical and spectroscopic characteristics of organic inclusions It is found that the organic matter involved in metallogenesis mainly comes from lower organisms such as bacteria and algae. The composition, structure and maturity of the organic matter in the fluid evolve along with the mineralization. Based on the analysis of organic carbon, gold content and algae mineralization simulation experiments, it is considered that the organic matter involved in mineralization mainly consists of activation extraction and sedimentation, while kerogen contributes to gold enrichment.
