STUDY ON TRANSFER STRUTURE IN JIAODONG REGION BY THE USE OF SPACEBORNE SAR LMAGE

Spaceborne SAR has an important effect on set pattem as used in dealing with the transferstructure. the image lamellae of ERs-1 SAR and JERS-1 SAR provide us with rich information of transferfractures and the distribution of key structures which can be directly used for dynamic and kinamatic analysis.Present study, taking Dong Ying-Xi Ling deformation zone as an example, including structue net analysis andmicrostructural lamella analysis proves that the deformation zone is a sinistral ductile shear zone in which thetranspression lineation and the transtension fracture are consistent with P shear plane and R shear plane respectively, The P plane related to gold mineralization is a high strain deformation belt. Detail work revealsboundary migration, grain-fine structure and mylonitic foliation of the granular qautz in the belt. The C axisof quartz grains and subgrains is highly oriented. We argure that the structure fracture and lamella shaped themicro geosurface, and the face direction of R shear plane quantified the echo of Radar wave. Because of thehigh relation of the structure lamella and the Radar lmage lamellae, the spaceborns SAR not only renewed thestructure research, but also created a new way to study the Radar image-forming mechanism and to establishthe modle of geo-element setting.
