| Abstract: | The reflector with large dip angles below Tertiary in the eastern part of Pearl River Mouth Basin is determined to be marine Mesozoic age by way of seismic data re-processing combined with the intepretation of gravity-magnetic data, drilling and regional geological information, and by comparing with cross well trunk line, interval velocity, outcrop data and samples, etc. Favourable areas for exploration and exploration targets are proposed in this paper as new exploration aspects by studying the structural features and distribution, analysing their hydrocarbon generation potential and by utilizing time-frequency analysis method to study the source-reservoir and seals. |
