非岩浆型被动陆缘研究进展及其深水盆地发育特征

作为当今全球油气勘探的热点领域,深水盆地发育于非火山型被动陆缘背景,其结构特征及演化过程与被动陆缘形成过程中岩石圈的变形作用密切相关。文中通过系统的文献资料调研,在总结非火山型被动陆缘研究现状和研究进展的基础上,阐述了非火山型被动大陆边缘的分类及其主要特征,详细介绍了非火山型被动大陆边缘演化阶段与构造单元的划分,从横向和纵向上描述了其深水盆地沉积特征,并简单探讨深水盆地构造-沉积演化过程。对非岩浆型被动陆缘研究进展及其深水盆地发育特征的总结,以期有助于深化对国内被动陆缘深水盆地结构特征和演化过程的认识,为深水油气勘探提供理论指导。

Research progress of magma-poor passive continental margin and characteristics of deep water basin

The deepwater basin,which developed in the magma-poor passive continental margin,has become a hot spot recently in global hydrocarbon exploration.The structural characteristics and the evolution process of the deep water basin are closely related to the deformation of the lithosphere during the passive continental margin formation.In this paper,through systematic investigation of the rich data of the latest progress and research status of magma-poor rifted margins,we try to show the tectonic evolution stages,tectonic unit division,the main types and its characteristics of the passive continental margin in details.This paper also illustrates horizontal and vertical depositional characteristics of the deep-water basin and explores the tectonic-sedimentary evolution of the deep-water basin.Summing up research progress of magma-poor rifted margin and development characteristics of deep water basin,the understanding of the structural characteristics and evolution process of magma-poor rifted margin deep-water basin of China is deepened,which provides a new idea for deepwater oil and gas exploration in China.
