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
