菜挤河后造山盆地构造演化特征

Structure evolution characteristics of post- orogenic basins of Caiji River

依据菜挤河的构造特征、各构造单元的基本特征、构造变形层次及变形序列、新构造运动、地质发展史,阐述了菜挤河地区后造山盆地的形成。该盆地具有沉积建造类型多样、变质作用类型复杂、火山岩浆活动频繁、地壳运动具多阶段、多层次的复杂构造格局等特征。

This discussed the characteristics of post - orogenic basins of Caiji River based on the tectonic features, the basic characteristics of the various tectonic units, level of tectonic deformation and deformation sequence, new tectonic movement and geological development history. The basin has a various sedimentary types, complex metamorphic, frequent volcanic activity, crustal movement with multi - stage, multi - level complex structural pattern and other features.
