摘要:

渤南洼陷是一个中—新生代形成的复合盆地,总体表现为北陡南缓的箕状坳陷。根据构造平衡与复原技术,结合洼陷的沉积和沉降特征进行研究,表明该洼陷的构造并不是一个简单的伸展构造,而是经历了不同时期构造背景的转换,从而形成了不同类型的反转构造,总的趋势是强烈拉张与弱挤压的交替。盆地周边的凸起与边界断裂对盆地内的变形和沉积作用起到了明显的控制作用。

关键词: 渤南洼陷, 平衡剖面, 反转构造, 盆地演化

Abstract:

Bonan depression is a complex basin formed during Mesozoic and Cenozoic. It is steep in north slope and gentle in south slope, which is controlled by listric faults. The balanced section technique is used to study its sedimentation and subsiding. It is indicated that the depression is not a sample extension structure, and the reverse structures were existed in different evolution stages. The intensive extension and weak compression were alternatively occurred during its evolution. The heaved blocks around the basin and the boundary faults controlled the deformation and sedimentation of the depression.

Key words: Bonan depression, balanced section, reverse structure, basin evolution
