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.

胶东地区星戴合成孔径雷达(SAR)图象具有丰富的转换构造(TransferStructure)信息.ERS-1SAR和JERS—1SAR的图象纹理以及图像处理分析结果,在胶东地区准确厘定了与转换作用有关的定性构造纹理,为动力学和运动学研究提供了极为重要的直观依据。现场调查以胶东地区的东尹-西林变形带为重点,配合显微构造研究和超微构造研究。证实了该变形带是一个东西向的左行韧性剪切带、其中剪切挤压构造(Transpression)和剪切拉伸构造面(Transtension)方位分别与剪面P和R的方位一致,与金成矿有关的P面方位为高应变带,带中石英晶体边界迁移显著,细粒化作用强烈,晶体C轴高度定向,糜棱面理发育。构造纹理控制了微观地表的几何形态,R面取向决定了雷达波的回波强弱雷达图像纹理与构造纹理的高度相关,不仅使星载SAR探测技术成为构造研究的重要手段,而且为雷达图像成像机理研究、地质体识别模型的建立提供了重要证据。
