西伯利亚克拉通或古西伯利亚台地,其面积4000000kin~2以上,是亚洲北部最主要的大陆地块之一.它以寒武系分布区域极为广瑟、层序非常完整为特色.寒武系构成了遍及全区的下沉积盖层和出嚣在大的正向构造内。寒武纪时,研究区是重要的碳酸盐沉积区,有碳酸盐一硅质碎屑的混合沉积、蒸发盐、礁和深水盆地的碳酸盐沉积.半个多世纪来,区内进行了各种大型的旨在找烃的地质调查及有关的寒武系层理、古地理和古构造的重建,以及沉积环境的重塑.但关于沉积物内部构造的研究工作一直主要是根据传统地层学的。连续地层柱“概念.有些工作者认为,古深度和地貌史或排列的各式各样的恢复不强调瞬时.只有最近10-15年,地下调查配合成因地层学和盆地分析概念的发展。使得有可能将生物群演化、沉积体边界的形状和类型以及它们的成因和对各种因素(诸如以上所述各种及相对海平面变化之类)的影响综合为统一的系统.这种区域继承观点的研究方法在60年代后期由 Grachevsky(1969)提出,然后由Savlstky(1979)和 Astashkiu(1984)详尽阐述,其目的是重建西伯利亚克拉通盆地充填和发展中的动力学. Siberian craton or ancient Siberia, with an area of ​​more than 4000000 km ~ 2, is one of the most important continents in the northern part of Asia, and it is characterized by a very broad and orderly distribution of the Cambrian. The lower caprock and clamor throughout the region are within the large forward tectonics. During the Cambrian period, the study area was an important carbonate deposition area with mixed carbonate-siliceous sediments, evaporites, reefs and carbonate deposits in deep-water basins. For more than half a century, Various large-scale geological investigations aimed at finding hydrocarbons and related Cambrian stratigraphy, palaeogeography and paleo-tectonic reconstruction, and remodeling of the sedimentary environment, research on the internal structure of sediments has been based primarily on conventional stratigraphy Learned. Continuous Stratigraphic Column. ”Some workers believe that various types of restoration of palaeo-history and topography or alignment do not emphasize momentaryity. Only in the last 10-15 years has underground surveys been accompanied by the development of genetic stratigraphy and basin analysis concepts. Making it possible to combine the evolution of biota, the shape and type of sedimentary body boundaries, their genesis, and their impact on various factors, such as the various and relative sea-level changes described above, into a unified system. The inherited approach to research was proposed by Grachevsky (1969) in the late 1960s and elaborated by Savlstky (1979) and Astashkiu (1984) with the aim of reconstructing the kinetics of filling and development in the Cratonic Basin of Siberia.
