Abstract: One of the difficult problems in rifted basin research is seismic strata comparison, and lack of area comparison criterion of seismic strata is the main reason which caused tracked seismic reflection disunion between each depressed area in Hailaer-Tamucage Basin. Based on the factors of seismic sequence, two kinds of sequence interface are classified in this issue，which including structuring interface（TE, TK2 , TK1n, TK1t and TJt reflecting horizon）seismic reflecting horizon（TK1y1 , TK1d2 and TK1d1 seismic reflecting layer），and the areal structure-strata framework is established according to the comparison criterion of seismic sequence. The genesis comparison method of seismic strata which is based on structural framework building is raised, which can solve the uncertainty both in structural

sequence interface and sedimentary sequence interface completely.

Key words:

strata comparison, structural sequence, sedimentary sequence, the genesis comparison method of seismic strata
