Study on sequence stratigraphy from benzi to taiyuan formation in Northeastern Ordos Basin

摘要：

Based on the study of the vertical sedimentary sequence, we recognize the assemblage of vertical lithology, the geochemical test result of mudstone sample, and the characteristics of logs, the sequence stratigraphic interfaces such as regional unconformity, regional tectonic regime interface, sedimentary system interface, transgression surface and so on. Benxi to Taiyuan formation formed in the epicontinental sea, which has subdued floor, so most of the sequence structures from Benxi to Taiyuan formation are duality system tract. Tectonic disturbance, sea level change, and differential compaction provide enough accommodation space for distribution of K1 sandstone and Qiaotou sandstone. At last we establish the framework and model of sequence stratigraphy from Benxi to Taiyuan formation in northeastern Ordos basin in this paper, which contains type I model of ramp marginal basin and type II of ramp in epicontinental sea background.
