裂谷地区的层序地层初探
|
摘要
自上世纪八十年代层序地层的概念被提出,九十年代进入理论与生产全面发展时期,至今大体上分为Exxon沉积层序理论学派,Galloway的成因地层学学派和T.A.Cross陆相高分辨率层序地层学理论学派,主要以陆相层序地层及海相层序地层研究为主要对象。国际上目前研究内容包括海相、湖相、河流相碎屑岩层序地层;碳酸盐层序地层;煤和其他沉积物层序地层研究,而国内以陆相河流相、湖泊相层序地层研究为主,对裂谷层序地层研究较少[1-6],虽然对于被动陆缘盆地层序地层学概念已提出,但裂谷地区层序地层还没有合适的沉积模式提出,本文从传统的层序地层原理及层序地层格架控制因素包括:野外露头、测井、地震等方面对裂谷层序地层进行分析,最后提出裂谷盆地的层序地层模型。
Since the 1980 s, the concept of the sequence stratigraphy is put forward, in the ninety s into the all-round development theory and the production period, school of today can be broadly divided into Exxon sedimentary sequence theory, Galloway school of genetic stratigraphy and T.A.C Ross school continental high resolution sequence stratigraphy theory, mainly continental sequence stratigraphy and Marine sequence stratigraphy research as the main object. On the international current research contents include Marine facies, lacustrine facies, fluvial facies clastic sequence stratigraphy; Carbonate sequence stratigraphy; Coal and other sediment sequence stratigraphy research, and domestic to continental fluvial facies, lacustrine facies sequence stratigraphy study is given priority to, the rift sequence stratigraphy research is less. Although the concept has been put forward for the passive continental margin basin sequence stratigraphy, sequence stratigraphy but rift valley region are still to be suitable depositional model put forward, in this paper, from the traditional principles of sequence stratigraphy and sequence stratigraphy framework control factors include: field outcrops, well logging, seismic sequence stratigraphy analysis of the rift valley, the rift basin sequence stratigraphy model is put forward.
