Abstract: With the application of the theory of highresolution sequence stratigraphy referred to the core and seismic and logging data, the sequence framework was established within the synrifting of Sunda basin based on the well to seismic calibration. Six sequence boundaries are identified by which five sequences are divided. At the same time, the source direction and sedimentary facies of each sequence are analyzed. The basin developed depositional system of fan delta, braided channel delta, fluvial, delta, Nearshore Subaqueous Fans and beach, which changed greatly in different time and position. Compared to the typical rifted basin in East China, Sunda basin has short duration of synrifting and seldom developed subsidiary fracture accompanying with the main fracture. The duration of lacustrine basin was shorter and the water depth was shallower than the basin in East China.
