| 摘 要： | 本文对采自衡山花岗岩体西缘韧性剪切带的标本进行了岩石磁性组构研究,并将其与常规应变分析方法所得结果予以比较,表明了岩石磁化率各向异性椭球体与应变椭球体之间有一定的对应关系,岩石磁化率各向异性技术可望成为构造地质学的一种新手段。岩石磁性组构资料可应用于变形岩石的应变分析,特别是在没有宏观应变标志或者通常的岩石组构分析方法太费时间的情况下更显出其优越性。

| Abstract: | A magnetic fabric study has been conducted for the samples from the ductile shear zone in western margin of Hengshan granite, and a comparison with the routine strain analysis has been made, which shows some correspondence relation between the anisotropy of magnetic susceptibility ellipsoids and the total strain ellipsoids.and the anisotropy of magnetic susceptibility technique is of prospect to become a new means for the study of structural geology. The petromagnetic fabric data is applicable to the strain analysis of deformed rocks, its superiority is shown especially in the cases of no visible strain markers or when the routine petrofabric technique is too timeconsuming. |
