Geochemistry in the Mineralizing Process of Laowangchang Lateritic- Type Gold Deposits of Southwest Guizhou |
| |
Abstract: | 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. |
