摘要:

论文在收集整理了大量地质资料的基础上,分析研究了川东北罗家寨构造的构造特征

,表明罗家寨构造是在川东高陡构造带和大巴山弧形构造的共同影响下形成的;罗家寨构造的

发育主要经历了四个主要构造时期,即印支运动中晚期、燕山运动期、喜马拉雅运动中期和喜

马拉雅运动晚期,其中喜马拉雅运动中期和喜马拉雅运动晚期是罗家寨构造形成的主要时期。

Abstract:

Based on the a lot geological data,the authors of this paper analyze the structure characters of the Loujiazhai

Structure in northeast Sichuan Basin.The results show that the formation of the Loujiazhai Structure is affected by the

steep structure belt of East Sichuan Basin and the Dabashan arc structure belt.The Loujiazhai Structure experienced four

major tectonic periods,the middle and the late Indosinian Movement,the Yanshan Movement,the middle Himalayan Movement and

the late Himalayan Movement.Among the four periods,the middle Himalayan Movement and the late Himalayan Movement are the

most important periods to the formation of the Loujiazhai Structure.

Key words: tectonic origin, tectonic period, Loujiazhai structure, Northeast of Sichuan, Dabashan
