摘要
This paper analyzes the structural style and assemblage configuration in Tuonamu area in Qiangtang Basin and suggests that there exist two structural styles of contraction and slip, and four assemblage configurations such as overthrust/nappe-like, broom-like,ring-like and radiat structures. The Tuonamu dome was formed by pre-contraction and post right-slip actions under unified SN trending stress field, as a reaction of local stress field under the boundary condition changes.
