宏、微观构造特征研究表明 ,红柳河地区造山期韧性变形大致可分两个阶段。早期形成南倾的面理、东倾的拉伸线理、鞘褶皱 ,变形具右行逆冲剪切特点 ,有限应变分析表明具压扁变形特征。晚期变形形成红柳河主干背斜、西倾的拉伸线理及红柳河—前进工区左行逆冲走滑剪切带。根据变形岩石和未变形岩石年龄确定变形期为加里东晚期—海西早期 ,变质变形特征显示变形层次属中浅构造层次 Macroscopic and microstructural studies show that the ductile deformation during the orogenic period in Hongliuhe can be roughly divided into two stages. In the early stage, the southern dipping facies, east dip ductile lineage, sheath fold, and dextral strike-shear thrusting characteristics were obtained. Finite strain analysis indicated that they were crushed and deformed. The late deformation formed the main anticline of the Hongliuhe River, the stretching line of the west dip, and the left-lateral thrust strike-slip shear zone of the Hongliuhe-Qianjin section. Based on the ages of deformed rocks and undeformed rocks, the deformation period is determined to be the Late Caledonian-Early Hercynian. The metamorphic deformation features show that the deformed layers are medium-shallow structural strata
