The present structural framework is mainly composed of a western Horse Racing Mountains (HRM) along-bedding detachment ductile deformation zone, Yonghong Mountains nappe and western HRM-Yonghong Mountains dome-basin.

The ductile deformation zone in Jiaoluotage area in Xinjiang Autonomous Region developed in E W trending Carboniferous volcanic and sedimentary formation between the Tuha Block and the Mid Tianshan Block,and comprises a set of E W striking and upright penetrative foliation.

Several ductile deformation metamorphism belts in E-W direction are recognized in the xenoliths (2.

The long large malleable shear deformable body in Gaowu area has different types and the geologic characters are distinctive.

X-ray diffraction analysis indicates that brittle deformation cannot bring about the change of the coal rank, but ductile deformation can and that temperatures are the main factor for raising the coal rank and the directional pressure acts as the "cataly.

The Jiaojia fault zone is characterized by ductile deformation in the early stage and brittle fracturing in late stage.

According to the study on the structural feature from macro to micro scale,the ductile deformation during orogenic period can be divided into two stages.
