| 摘 要： | 通过对青峰韧性剪切带中糜棱岩的磁性组构研究,同时与常规主应变分析方法所测结果比较,表明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。磁性组构的特征为构造岩变形机制,以及断裂带的运动学、动力学等的研究提供了一种比较可靠、准确、方便的方法。

| Abstract: | The study of magnetic susceptibility anisotropy techniques as a petrofabric element has shown that the magnetofabric data are applicable to the strain analysis in the deformed rocks for which the standard petrofabric techniques are too cursory and time-consuming. The magnetic fabric of some samples from Qingfeng ductile shear zone was determined by means of the anisotropy technique and a comparison of the magnetic fabric data with the available strain data was made. This indicates that the magnetic suscepibility anisotropy ellipsoids coordinate with the total strain ellipsoids. This new and rapid technique can be applied to study of petrologic deformation mechanism, kine matics and dynamics of fault zone. |
