摘要/Abstract

摘要： 从渤海湾盆地的几何形态、盆地边界的走滑构造和内部的伸展构造分析，结合盆地的沉积特征和深部地质特征的研究，提出渤海湾盆地的拉分构造成因模式。渤海湾盆地可以划分为三个构造区带：东、西两个走滑构造带和一个中部拉分构造区。从渤海湾盆地的中、新生代构造演化分析，渤海湾盆地是一个新生代早第三纪始新世形成的走滑拉分盆地。这个走滑拉分盆地的中部发育伸展构造，这些伸展构造是由走滑作用派生而来的。中生代就已存在的东西两个走滑构造带是新生代形成渤海湾走滑拉分盆地的基本地质条件。

Abstract: The origin model of Bohai Bay basin is proposed on the basis of analyzing the boundary pattern, strike-slip and extensional structures, deposit and deep geology characteristic on the boundary and in the basin. Bohai Bay basin can be classified into three tectonic belts(or areas): two strike-slip tectonic belts on eastern boundary and western boundary and a central pull-apart extensional area. According to the analysis of Mesozoic and Cenozoic tectonic evolution, Bohai Bay basin is a strike-slip pull-apart basin formed in the Cenozoic Eocene epoch. The extensional structures developed in the central Bohai Bay basin are induced by strike slip. The eastern and western strike-slip tectonic belts are basic geological conditions to form the Cenozoic Bohai Bay strike-slip pull-apart basin.

Key words: Bohai Bay basin, strike-slip pull-apart basin, extensional structure, Yanliao-Taihang-Zhongtiao faul zone, Tanlu fault zone
