文章主要对西西伯利亚地台上的古生代盆地和阿尔泰一萨彦岭古生代盆地中古生代碳酸岩盐台地沉积环境的分布范围和地层发 育情况进行了分析。研究了在这类环境中所形成的各种生物沉积结构的生物碳酸盐岩连续沉积带。在这类沉积带中发育有少量的链状 礁和礁块,某些礁块是由古老礁块继承发育而成。研究了礁体上覆、下伏碳酸盐岩储集层和陆源成因的流体遮挡层,阐述了上述两个盆地 礁岩形成的同期性,这可能与统一的西伯利亚古海湾的存在有关。
The article mainly analyzes the distribution range and the stratigraphic development of the sedimentary environment in the Paleozoic basins on the western Siberian platform and the Mesozoic carbonatite platforms in the Altay-Sayanling Paleozoic basin. A series of bio-carbonate sedimentary zones of various bio-sedimentary structures formed in such environments were studied. In this type of sedimentary belt developed a small amount of chain reefs and reefs, and some reefs are inherited from the ancient reef development. The fluid occlusions of overlying and underlying carbonate reservoirs and terrigenous origin in the reef are studied. The synchronicity of reef formation in the two basins above is expounded, which may be related to the existence of a unified ancient Gulf of Siberia.
