SUMMARY

Some tectonic features of faults and recent movements in West Bắc Bộ

Phan Văn Quýnh, Hoàng Hữu Hiệp

Although recent tectonic movements (10,000 years) are closely related to Neotectonic phases, they have individual character of tectonic stress field and the regime of dynamics and kinematics. North-south deformation system and gravity difference are the features of recent tectonic development in West Bắc Bộ. According to these characteristics, in the studied area there are many dynamic blocks of high order and at the same time happen the strike-slip along Northwest fault system and gravity slide. The paper presents also the difference between Neotectonic and recent tectonic movements.
