摘要
煤镜质组反射率及其各向异性、共轭剪节理、充填脉和小褶曲等构造形迹,是煤田构造应力场研究中实用和有效的形变标志物。本文详细论述了上述标志物的基本特征及其在煤田构造应力场研究中的应用,尤其强调了煤镜质组反射率各向异性分析技术作为煤田构造研究的一种新方法,用于应力场分析的重要意义。
The practical and efficient deformation indicators in study of tectonic stress field in coalfields are: coal vitrinite reflectance and its anisotropy, conjugated shear joints, filled-in veins an small folds. This paper discusses in detail the basic characteristics of these indicators and their application in investigation of tectonic technology for analyzing vitrinite reflectance anisotropy,which is a new approach for studying coalfield structures and is of significance to the study of tectonic stresses field.
