印尼Sunda盆地裂陷期层序地层与沉积充填特征
|
摘要
应用高分辨率层序地层学原理和分析方法,以岩心、测井、录井、地震和分析化验资料为基础,通过Sunda盆地古近系层序地层关键界面的识别与对比,建立了盆地裂陷期层序地层格架。Sunda盆地裂陷期发育6个具有等时意义的层序界面,将其划分为5个长期基准面旋回。在盆地结构分析的基础上,确定了主要物源方向,分析了各个层序的沉积特征,认为盆地主要发育有扇三角洲、河流—三角洲、近岸水下扇、滩坝等沉积体系,不同层序发育时期及盆地的不同位置,其沉积体系类型及其分布有较大差异。与渤海湾盆地典型单断箕状断陷盆地相比,尽管断陷结构有相似性,但Sunda盆地裂陷期沉降速率相对较低,持续时间较短,深水湖泊发育规模相对较小。由于与盆缘主控断裂伴生的次级断裂不发育,沉积体系类型与发育特征也与典型的断陷盆地有较大的区别。
With the application of the theory of high-resolution sequence stratigraphy referred to the core and seismic and logging data,the sequence framework was established within the syn-rifting of Sunda basin based on the well to seismic calibration. Six sequence boundaries are identified by which five sequences are divided. At the same time,the source direction and sedimentary facies of each sequence are analyzed. The basin developed depositional system of fan delta,braided channel delta,fluvial,delta,Nearshore Subaqueous Fans and beach,which changed greatly in different time and position. Compared to the typical rifted basin in East China,Sunda basin has short duration of syn-rifting and seldom developed subsidiary fracture accompanying with the main fracture. The duration of lacustrine basin was shorter and the water depth was shallower than the basin in East China.
