摘要
对广东长坑金银矿床流体包裹体的研究表明 ,该矿床矿石中流体包裹体种类较多 ,以富气态烃包裹体与盐水溶液包裹体为主 ,包裹体相对含量统计表明 ,富气态烃包裹体占包裹体总数的大多数 ,表明成矿流体为富含气态烃的水溶液。金、银矿石均一温度测定主要集中在 16 0～ 2 6 0℃区间。单个包裹体的拉曼光谱分析结果证明 ,成矿流体成分与赋矿围岩有密切关系。
There are several types of fluid inclusions in the deposits. Relative content of different types of inclusions show that fluid inclusions are mainly organic. The ore forming fluids are the organic gas rich with salt water. Homogenization temperature of the deposits are 160~260℃ mainly, but the salinity of gold ore forming fluid is higher than that with silver. So they are in different stages. Raman spectrum of inclusions shows the composition of ore forming fluid has closely related to the country rocks. Ore forming fluid is the organic rich basin fluid.
