构造地质研究中应用x光岩组方法需注意的几个问题

BRIEF NOTE ON THE APPLICATION OF X RAY DETERMINATION OF PETROFABRICS TO STRUCTURAL ANALYSIS

本文简述了ｘ光岩组分析的特点和样品的选择，重点阐述了石英组构特征与岩石整体变形及石英矿物粒内变形的关系。在介绍石英ｘ光极图转换成石英光轴图的方法之后，作者运用实例说明了将ｘ光岩组方法与其它显微构造及组构方法（如费氏台岩组测量）结合起来。

In this paper,the authors first describe the characteristics of x ray determination of petrofabrics and selection of the samples,and proceed to discuss the relation of quartz fabric to the deformation of rocks and of the quartz grains themselves.After demonstrating how to transform quartz(1010) polar digrams to the sketch of quartz optic axis,an example is taken to illustrate that a combination of x ray determination with other microstructural analysis or fabric study will yield more information for the research of geological structures.
