显微构造研究方法在韧性剪切带遥感分析中的应用

Application of Microstructure Research Methods to Remote Sensing Analysis on the Ductile Shearing Zone

通过对东天山地区韧性剪切带宏观构造特征和显微构造特征的对比,证明区域构造和显微构造在几何学和运动学方面具有相似性;进而采用显微构造研究方法,借助遥感技术对该区的韧性剪切带进行了研究。在构造样式、运动指向、位移量方面,研究结果均与前人在同一地区的野外调查及显微鉴定成果基本吻合。因此,一种变形机制下形成的不同尺度的构造形迹,存在高度相关的内在成因联系;对于不同的观察平台,构造尺度的大小是相对的。遥感与显微技术相结合是一种比较实用的新型构造研究方法。

By comparing the regional structure to microstructure of ductile shearing zones in eastern Tianshan area,it is proved that they are similar in both geometry and kinematics.Then the research methods of microstructure,together with remote sensing,was applied to the researching of the ductile shearing zone.The results of structure analysis are accord with such data achieved in both field survey and micro-observation,as structure patterns,direction and displacement of the movement.It can be concluded that structures with different size,resulted from the same deforming mechanism,have obvious correlation,and the tectonic size is comparative in the different observing scale.The combination of the remote sensing and the micrology can be listed as a new method of tectonics study.
