| 摘 要： | 笔者通过流体包裹体的岩相学、显微测温学以及激光拉曼成分的对比研究,探明了大桥坞铀矿床成矿流体的基本性质（温度、盐度及成分）,结合该矿床的构造和地质-地球化学特征,对成矿流体的来源进行了探讨。研究结果表明,该矿床主成矿期成矿温度为200-250℃,属于中温热液矿床,其成矿流体为富含CO2、H2、CH4等气体组分的中高盐度流体,反映该矿床成矿过程以深部流体作用为主,成矿流体主要为来自地幔的流体。 |

| Abstract: | This paper describes a new method of calculating mineral composition in rocks.The new method combines microscopic observation of thin section and chemical total analysis of rocks according to theprinciples of molecular weight method.The mineral composition achieved by the new method is in the form of waight percentage of various minerals in the three-dimensional volume of a rock,which is much more accurate than the current used visual method by measuring the area percentage of minerals in a section plane,and is more consistant with the actual situation of mineral composition in rock samples.The new method is also applicable to calculating mineral contents of altered and mineralized rocks,that containing mica,chlorite and uranium minerals granite,sedimentary and metamorphic rocks. |
