摘　　要：根据地质地球化学研究所揭示的与成矿地球化学作用有关的宏观和微观特征 ,对老万场金矿的物质来源和成矿过程的地球化学作用进行了讨论 ,阐述了成矿 (成土 )过程中Au和相关元素的地球化学行为以及本类红土型金矿形成的地球化学机理。指出了喀斯特红土化作用在原始卡林型金矿风化成土过程中对红土型金矿形成的影响。According to macroscopic and microscopic features related to geochemical action in the mineralizing process unveiled by geochemical study, this paper discusses material sources of Laowangchang gold deposit and the geochemistry in the metallogenic process, and expounds the geochemical behavior of Au and correlative elements together with the geochemical mechanism of formation in the lateritic gold deposit. It is indicated that the karst lateritization to influence on formation of the lateritic gold deposit has been formed in the process of weathering and soil-formed of original carlin-type gold deposits.
