在对湘西低温矿化区中含矿建造的地球化学研究及典型矿床成矿流体性质的比较研究后指出,由元古界板溪群内发育的An、Sb矿化至古生界寒武系内的Hg矿化,其矿化流体具有硫浓度不断降低,氯浓度显著升高,大气降水的比例不断增加的明显规律。含矿建造中成矿元素的丰度为控制矿化类型的非主要因素,成矿流体中矿化剂的种类和浓度以及成矿温度则是制约该区矿化类型的主要地球化学机制。
After studying the geochemical study of ore-bearing construction and ore-forming fluids in typical ore deposits in low-temperature mineralized area in western Hunan, it is pointed out that the mineralization of An and Sb developed from Banxi Group in the Proterozoic to the Paleozoic Cambrian Within the mineralization of Hg, the mineralized fluid has the obvious regularity of continuously decreasing the sulfur concentration, increasing the chlorine concentration and increasing the proportion of the precipitation in the atmosphere. The ore-forming element abundance is the non-main factor controlling mineralization type. The type and concentration of mineralizing agent and the metallogenetic temperature in ore-forming fluid are the main geochemical mechanisms that restrict the mineralization type in this area.
