Abstract:

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.

Key words: microstructures, similarity, remote sensing, ductile shearing zone, strain analysis, eastern Tianshan area
