摘要:

中国南方在泥盆、石炭纪时,裂陷运动在被动陆缘和陆内产生许多裂陷槽,形成相对于浅水碳酸盐台地的台间斜坡—海槽深水沉积环境。台间海槽可分为继承性深水台间海槽和泥盆纪时发育起来的台间海槽;台缘斜坡分为跌积边缘型和沉积边缘型。文章描述了上述各深水环境相特征。从区域构造背景和海槽分布方向性、分组性、火山活动、断裂差异升降方面论述了斜坡—海槽的构造活动性。斜坡—海槽的深水沉积环境和岩相,提供了油气生成、储集、运移、圈闭、聚集和保存的有利条件。

Abstract:

During Devonian and Carboniferous Periods in South China, taphrogeny originated many taphrogenic troughs, thus forming some slope-trough deep-water depositional environments between shallow cabonite platforms in the passive continental margin and the interior continent. The troughs between platforms may be classified as the succesive deep-water trough and the trough developed during Devonian. The slopes of platform margin are classified as by-pass and depositional margin types.The facies characteristics of above-mentioned depositional environments are described in this paper.The tectonic activity of the slope trough environments are deseribed on the basis of regional tectonic background and the directions,groups,volcanic activity,and differential lift or face of faulting.The slope-trough deep-water depositional environments and facies are favourable to the formation,reservoir,migration,trap,accumulation and preservation of oil and gas.
