Abstract

The Pearl River Mouth basin is the largest pre-Cenozoic sedimentary basin on the continental slope of the South China Sea. It is rich in oil and gas resources. Due to the lack of new geophysical data, the distribution characteristics of the internal tectonic units in the Pearl River Mouth basin have many different views. This problem has constrained further exploration and development of the basin. This study aims to throw light on the magnetic basement structure of Pearl River Mouth basin based on the latest high resolution aeromagnetic data, combined with drilling data, seismic profiles and basic geological data. Tangent method was used in the inversion. On the basis of fully investigating the existing structural unit division in the Pearl River Mouth basin and in combination with the faults and regional structures, the internal tectonic units were studied. The result shows that the magnetic basement depth of the basin is between 0 and 9 km, and the magnetic basement is characterized by "three uplift and two depressions". The whole depression area has the characteristics of "north-south zoning, east-west sub-block". The NE trending fault is the main fault that controls sedimentary depression, while the NW-trending faults are secondary faults which control depressions.

Key words： Pearl River Mouth basin tectonic unit magnetic basement basement rift
