| 摘 要： | 介绍根据显微下观察,应用岩石化学全分析结果和分子量计算法计算岩石中矿物组成的新方法。所得各种矿物的组成是整块岩石在三维立体体积中各种矿物的质量分数,比目前沿用的目测一个岩石切面上各种矿物的面积百分比法更准确,比CIPW标准矿物分子法更符合岩石样品组合的实际情况,而且可用于含云母族、绿泥石族和铀矿物等蚀变矿化的花岗岩及沉积岩、变质岩的矿物组成计算。

| 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 the principles 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 . |
