| 摘 要： | 文本总结了对采自巴彦乌拉山韧性剪切带的部分标本进行岩石组构数据测定的分析结果,并将其与用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能够反映总的应变椭球体,证明岩石磁化率各向异性技术做为一种岩石组构因素的研究是有发展前景的。岩石磁性组构资料可应用于变形岩石的应变分析,特别是在通常的岩石组构分析技术太费时间和粗糙的情况下更显示了其优越性。

| Abstract: | The study of magnetic susceptibility anisotropy techniques as a pectrofabric element has shown that the magnetiefabric data are applicable to the strain analysis in the deformed rocks for which the standard pctrofabric techniques are too cursory and time-consuming, The magnetic fabric of some samples from a thrusting ductile shearing-belt within Bayanwula Mountain was determined by means of the anisotropy technique and a comparison of the magnetic fabric data with the available strain data was made, which indicates that the magnetic susceptibility anisotropy ellipsoids reflect the total strain ellipsoids and therefore this new, rapid technique can be applied to strain analysis and structural geology. |
