The theory of the coal bed as the stratigraphic sequence border in a continental basin has been put forward abroad. For the purpose of combining this theory with the specific circumstances of the continental basin in China, we apply this theory to the study of the sequence stratigraphy in the Hongtai area, Tuha basin. We utilize the information about logging data, drill core and drilling data to analyze the division of lithostratigraphy and the sedimentary facies in the study area. The research formation is Sanjianfang Formation and Qiketai Formation in Middle Jurassic. And the main sedimentary facies are shore shallow lacustrine subfacies and braided river delta facies. There are two coal developing stages of LST in the study area, and each stage presents the cyclicity feature, the siliciclastic content in the coal bed also presents the cyclicity feature, so the coal bed as the stratigraphic sequence border in continental basin in China is feasible. Finally, we divide stratigraphic sequence in the work area, and the research formation is divided into two and half third order sequences.
Key words： Tuha basin; Hongtai area; Stratigraphic sequence; Coal bed; Identification sign.
