     In order to establish the isochronic stratigraphic frame of the fault basin, on the bases of the synthetical analysis of the seismic, drilling and outcrop data of Hailar Basin, two types of the structural and sedimentary un- conformities are identified from the viewpoint of the genesis of the unconformities： six structural unconformities （ To2, To4, T22, T3, T4 and T5 ） and two sedimentary unconformities （ T2 and T21 ） . The distinction of the uncon- formities can make the unification of the tracked seismic reflection formations among the sags of the basin, thus the stratigraphic correlation, sedimentary system tract and facies analysis can be ensured in the stratigraphic frame; in the meantime, the unconformities are the important channels for the hydrocarbon migration, many kinds of petrole- um reservoirs such as buried hill, structural-stratigraphic and faulted-block ones are discovered in the traps of top and bottom of the unconformities.
