据岩石组合、基本层序特征 ,结合生物化石鉴定和同位素测年结果 ,红柳河地区海西期物质建造由红柳河群海相碎屑岩、碳酸盐岩、火山岩建造和陆相磨拉石建造组成 ,主期变形形成主干褶皱———红柳河向斜及伴生构造 ,变形机制为纵弯褶皱作用兼具一定压扁特点 ,总挤压收缩率达 40 %～ 70 % ,反映了造山后强烈陆内收缩变形特点。构造演化时限为 35 6～ 2 5 6Ma。 According to the rock assemblage and basic sequence features, combined with the biological fossil identification and isotopic dating, the Hercynian material in the Hongliuhe area was constructed from the Hongliuhe Group marine clastic rocks, carbonate rocks, volcanic rocks and terrestrial molasse The main deformation is the main fold of the Hongliuhe syncline and its associated structure. The deformation mechanism has the characteristics of buckling and buckling. The total compression shrinkage reaches 40% ~ 70% Strong intracontinental contraction deformation characteristics. The tectonic evolution time is 35 6 ~ 25 6Ma.
