摘要
Based on the sedimentary characteristics, seismic reflection characteristics and regional stratigraphic thickness changes, this paper discusses the depositional framework of the Early-Middle Ordovician in Tazhong and Gucheng areas where two isolated platform margin-slope systems are existed respectively, between which is separated by a relatively low Zhonggu trough. Such a depositional framework discovery is an important significance to exploring and delineating the platform margin high energy facies of the Middle-Lower Ordovician and expanding the oil and gas exploration blocks in these areas.
