| 摘 要： | 金牙金矿是桂西北微细粒浸染型金矿床具有代表意义的典型矿床。其赋矿层位为三叠系中统百蓬组的富有机碳的浊积岩系。通过对成矿过程中有机包裹体的激光拉曼分子微探针研究认为:(1)有机质在成矿过程中会发生热降解,其降解产物烃的量可衡量热的程度;(2)无机组分和CO2/CH4 参数可用于研究热液的地球化学环境。

| Abstract: | Jinya gold deposit being one of typical micro-grain disseminated gold deposits in northwestern Guangxi, occurred in turbidite of Baifeng Formation of Middle Triassic Epoch and is controlled by tectonic fractured zone between fault F 1 and F 2. The depositis rich in organic carbon probably showing that gold metallization is associated with organic matter. Therefore,it is significant to study organic inclusions being associated with metallization. The four samples of 1502-B, 1502-D, 1504-C and T-1 were collected from drill hole 1502 with depth of 145m, drill hole 1502 with depth of 260m, drill hole 1504 with depth of 402m and outside the mine area, respectively. The samples were studied by Laser Raman Molecular Microprobe (LRM) and the concentrations of some compounds of organic inclusions are shown in Table 1 and Table 2. Some conclusions were suggested by analyzing the concentrations of hydrocarbons, inorganic compounds, parameters of CO 2/CH 4 and the ingredient characteristic of T-1 as follows:(1) Organic matter thermolysis will take place in metallization and products hydrocarbons and the yield of their hydrocarbons may be used to measure thermal degree; and (2) inorganic compounds and CO 2/CH 4 may be applied to search hydrothermal environment of geochemistry. |
