The concept of sequence style is suggested, and the basic catalogues and characteristics of sequence style in the Mid Yangtze area are studied in this paper. The result shows that there are three styles called T, H, and TH. They have marked different characters of sequence and deposition, and mechanics of formation. The conditions of reservoir formation are discussed from the angle of sedimentology , and an important relationship between them have been recognized. In craton sedimentary areas, the transgressire system tracts (TST) of H style is mainly related to source rocks and nice cap rocks , and the highstand system tracts (HST) of T style is generally related to reservoirs.
