在对贵州赋存于沉积岩中的微细浸染型金矿床地质地球化学和元素组合研究基础上，并与卡林金矿床对比后拟定的低温开放体系中金矿成矿的初步模拟实验表明，该体系中元素主要是由构造动力驱动从高压区向低压区迁移，并在迁移过程中按元素地球化学性质和成矿条件变化形成沉淀分带；金氯络合物的分解和成矿物质的沉淀与黄铁矿和有机质明显有关；元素的变化趋势呈非简单线性关系，有机质受到热变质作用，且变质作用不同对金成矿有一定影响
Based on the geo-geochemistry and elemental assemblages of the finely disseminated gold deposits hosted in sedimentary rocks in Guizhou and the preliminary simulation experiments of the gold mineralization in the open-cold system at low temperature developed after comparison with the Carlin gold deposit, it is shown that this system The middle element mainly migrated from high pressure area to low pressure area by tectonic driving force and formed sedimentary zonation according to elemental geochemical properties and metallogenic conditions during the migration process. The decomposition of gold chloride complex and precipitation of metallogenic material and Pyrite and organic matter are obviously related to each other. The trend of element is non-simple linear relationship, organic matter is subjected to thermal metamorphism, and metamorphism has some influence on gold mineralization
