摘要:

本文比较详细地论述了镜质组反射率体的几何性质和数学方程,以及利用若干实测数据计算出向量 Rmax、Rint、Rmin的大小和方位的方法。本文成果可应用于煤岩学、石油地球化学和构造地质学的有关研究工作。

Abstract:

Vitrinite reflectances may be described by vectors starting from the originof three-dimensional coordinate-system.The length of a reflectance vectordepends on its direction.Theoretically,any vitrinite particle has infinite reflec-tance vectors.These vectors construct a three-dimensional figure called“vitrinitereflectance solid”(VRS).The three principal axes of VRS are maximum ref-lectance Rmax intermediate reflectance Rint and minimum reflectance Rmin res-pectively.The VRS may be double concave,and is not a standard ellipsoidof geometry.This paper deals with the geometrical features of VRS in detail,and provi-des a method for determining the lengths and directions of the principal axesby six readings measured on three mutually perpendicular polished-surface.This method may be used for the studies of petroleum geochemistry,coalpetrology and structural geology.
