3 500 km of shallow seismic profiles were acquired in 2015 from the northern seas area of Fujian province. Interpretation is made systematically based on the sequence stratigraphy and seismic stratigraphy for the sediment deposited since late Pleistocene.According to previous researches and related results, the seismic profiles of the study area may be divided into 5 main seismic units, namely SU1, SU2, SU3, SU4, SU5 from top to bottom by 6 interfaces of QT1, QT2, QT21
, QT3, QT31
and QT4 respectively. Detailed descriptionis are carefully made for both the seismic units and the reflection interfaces. Rational inference is also made for the depositional history of the region.
