| Abstract: | As exemplified by lamprophyres in Laowangzhai gold deposit, Yunnan Province, this paper discussed the degassing in the processes of mantle derived magmatism based on the study results of the regional tectonic setting, mantle metasomatism, liquid immiscibility of silicate carbonate melts during magmatic evolution, the source of CO 2 in rocks, the characteristics of altered fluids, the relationship between rocks and gold mineralization, and experiments at high pressure and temperature etc. |
