TAILIEUCHUNG - Báo cáo " Mechanism of forming the Dien Bien basin "

The Dien Bien basin in the Northwest of Vietnam is the largest one of the pull-apart basins related to the Dien Bien - Lai Chau fault zone. This basin, orientated from the north to the south, is 21km long, 6-8km wide and rhomboidal in shape. The process of forming this basin is related closely to the activities of the Dien Bien - Lai Chau fault zone in Neotectonic time. On analyzing information concerning the kinematics of the Dien Bien - Lai Chau fault zone, the geological structure and the sediments of the basin, we suppose that the Dien. | VNU Journal of Science Earth Sciences 23 2007 76-79 Mechanism of forming the Dien Bien basin Chu Van Ngoi Luong Thi Thu Hoai College of Science VNU Received 12 March 2007 Abstract. The Dien Bien basin in the Northwest of Vietnam is the largest one of the pull-apart basins related to the Dien Bien - Lai Chau fault zone. This basin orientated from the north to the south is 21km long 6-8km wide and rhomboidal in shape. The process of forming this basin is related closely to the activities of the Dien Bien - Lai Chau fault zone in Neotectonic time. On analyzing information concerning the kinematics of the Dien Bien - Lai Chau fault zone the geological structure and the sediments of the basin we suppose that the Dien Bien basin is a splay pull-apart one related to the movement of the Dien Bien - Lai Chau fault zone in Pliocen-Quaternary time. The determination of the mechanism of forming the Dien Bien basin is important to specify Neotectonic activities of the Dien Bien - Lai Chau fault zone. Keywords Active tectonics Dien Bien - Lai Chau fault zone Pull-apart basins Quaternary. 1. Introduction The Dien Bien basin 21km long and 6-8km wide is an important political economic and cultural center of the Northwest region of Vietnam in general and of the Dien Bien Province in particular. In geological respect the Dien Bien basin is a small narrow rhomboidal pull-apart basin stretching along the Dien Bien - Lai Chau fault zone which is more than 160km long 6-10km wide and is the most seismically active fault zone in Indochina. Being an important center of the Northwest region of Vietnam the Dien Bien basin has been studied in detail for many years. However the dynamic model of forming this basin is still a knotty question for scientists who study the movement of the Dien Bien - Lai Chau fault Corresponding author. Tel. 84-4-5587060.
