区域构造联合/复合变形场与应力场遥感图像“分层”解析理论及方法

Remote sensing images display mainly the last results of tectonic movements in the geological history of an area，it certainly records identification information on tectonic deformations in the periods. In this study, aiming at some problems in the traditional geological method of recovering structural stress field and deformation field and based on our many research results and practices on the structural deformation, with comprehensive analysis of the structural deformation field characteristics of some typical structural compounding- combine deformation areas in the Sichuan, Guizhou provinces, a new theory and method for recovering regional tectonic stress field and deformation field phase-separation analysis method of remote sensing image information would be proposed. The phase-separation analysis method of remote sensing image information for regional tectonic stress field and deformation field is a means by which, macro-folds, related major transverse tensional joints, major conjugate shear joints, and other fractures which can reflect regional tectonic stress state are systematically and phase separately interpreted with the remote sensing images based on the dialectical relationship between remote sensing image factors and the phase-separation principle of geological interpretation of remote sensing images. The tectonic deformation fields are then determined through a comprehensive analysis of the macro-structures, the related fracture system, the distribution of those joints in space, and their relation to the tectonic deformation. Finally, according to the characteristics of the tectonic deformation field, the structural stress states during different periods of rock deformation are reconstructed, and related stress fields are recovered. The method is mainly suitable for areas of buckle folding. The research result broadens the theoretical basis and new application ideas of remote sensing geology and structural geology，and it takes a very important science place on structural geology，geological mechanics and other disciplines' theoretical research。Meantime，the result has an extensive application prospect on practical work such as petroleum geology，seismic geology and prospecting exploration etc.
