| 摘 要： | 通过对西昌盆地的沉积演化历史的初步研究.把西昌盆地的发展分为3个大阶段:基底形成阶段、被动边缘发展阶段和内陆盆地演化阶段,并细分为盆地基底形成阶段、被动边缘发展阶段、残海发展阶段、前陆盆地发展阶段、内陆拗陷盆地发展阶段、盆地萎缩阶段和盆地改造阶段等7个小阶段.每个阶段都有各自不同的沉积环境和沉积组构,这主要受控于构造运...

| Abstract: | Evolution of the Xichang basin may be divided into 3 stages such as basement formation stage,passive continental Mar.gin stage and inland basin stage which may be subdivided into 7 sub-stages such as basement formation,passive continental Mar.gin,relic Mar.ine,foreland basin,inland basin,basin shrinkage and basin reformation.Every stage or sub-stage is characterized by its special sedimentary environment and depositional fabric controlled by tectonism and faulting. |
