During the study of sequence stratigraphy in thenorthpart of Tarim Basin，a series ofhigh frequent progradational sequences have been discoveried in the seismic sections ofCambrian and Carboniferous.

Applying the theory and method of high resolution sequence stratigraphy, we have set up a high frequency sequence framework with high resolution for Dongying delta, and have studied the evolution of delta, and the types of slope break and the relationship between various delta stages and slope break zones.

In the upper of the high system tract,at least 5 high frequency sequences have been recognized.

By singal well analysis of high frequency sequence, the upper member of Eh 3 of Biyang fault_depression can be classified into three terrigenous \{sequences\} and nine systems tracts,or into four basic types and thirteen parasequence sets, of which there are fifty recognizable parasequences.

Analysis of high-frequency sequences and sea-level change of the Middle Jurassic Matuo Formation in the Yanshiping area,northern Tibet;

Based on 3D-seismic and well logging data,ten high-frequency sequences,i.

Based on the geological and geophysical data, this paper analyses characteristics and controls of high-frequency sequences of Lower Cretaceous Series in Wuerxun Depression.

Based on the high resolution sequence stratigraphical theory, this paper analyzed the variety of base level cycles and its control on the development and evolvement of Dongying delta.
