四川布拖地区小江断裂带构造特征及其演化
|
摘要
小江断裂带为川滇地块、华南地块的边界断裂,是一条重要的活动断裂。小江断裂带呈南北向纵贯研究区,由一组总体西倾、局部东倾的逆断层组成。该断裂带地质构造发展与演化史较为复杂,自古元古代至全新世经历了多期次的活动,对不同时期的地质事件均发挥了重要的控制作用。
The Xiaojiang Fault Zone as the boundary fault is considered as an important active fault between the Sichuan—Yunnan and South China block. The Xiaojiang Fault Zone is a north—south longitudinal study area,consisting of a group of reverse faults with a total westward dip and partial eastward dip. The geological structure development and evolution history of this fault zone is rather complicated. It has played an important role in controlling geological events in different periods.
