准噶尔盆地侏罗系露头层序地层及沉积学特征

Research on the Terrigenous Outcrop Sequence Stratigraphy and Sedimentology in the Jurassic Junggar Basin

在经典层序地层学理论以及成因地层学和河流沉积体系构成单元等级界面分析方法指导下 ,通过准噶尔侏罗系陆相盆地露头层序地层和沉积学的实际调查和综合研究 ,依据研究区沉积地层特征、层序和界面识别与划分、凝缩沉积、体系域和层序格架发育特点等 ,提出了陆相环境中层序地层研究以及层序界面、层序及凝缩层、体系域和层序格架识别与划分的若干标志及实际操作的指导原则和具体方法。

On the basis of the traditional concept of sequence stratigraphy by Vail P R(1977),genetic stratigraphy by Galloway(1990) and the conditional units of fluvial depositional system of Mail(1996),this paper,by applying studies on the outcrop sequence stratigraphy,such as,deposition,boundaries,condensed sections,system tracts and sequence framework of Jurassic Junggar basin,gives the general features,econgnized critics and research methods,procedures of terrigenous sequences.
