摘要
本文以苏里格东部地区奥陶系马家沟组马五5亚段为研究目标,根据岩性、沉积构造等相标志,以实测地层剖面、岩心观察、薄片鉴定等资料分析为手段,分析其沉积相特征。经过分析得出研究区发育碳酸盐岩台地沉积相,局限台地亚相发育在研究区的大部分地区,呈东北西南向线状发育,开阔台地亚相发育在研究区的东部区域,蒸发台地亚相的产物被剥蚀,并细分出七个沉积微相。
This paper takes M55 Sub-member of the Ordovician Majiagou Formation in the eastern Sulige Area as the research object.Based on lithology,sedimentary structure and other facies markers,the characteristics of sedimentary facies are analyzed by means of data analysis of measured stratigraphic section,core observation and thin section identification.Through analysis,it is concluded that carbonate platform sedimentary facies developed in the study area.Limited platform subfacies developed in most areas of the study area,linear development from northeast to southwest.The open platform subfacies developed in the eastern part of the study area.The products of evaporative platform subfacies are denuded.And seven sedimentary microfacies are subdivided.
