Abstract: Ignited by the existence of fluvial, wavy, tidal sediments deposited together in Pearl River mouth-Modaomen, and the land-ocean interaction theory, considering the reality of microfacies definition of delta, we introduced the hydrogeology, geography and geomorphology in to the delta-define scheme, and suggested to integrate fluvial, wavy and tidal microfacies, to re-organize the depositional elements to reconstruct marine delta. This scheme also reveals that referring to the neighbor science like hydrogeology, geography and geomorphology can be fruitful for sedmentological research, especially for petroleum exploration. Based on the field research on Modaomen, those sand bodies which distribute various styles on different orientation show that when we correlate the sand layers during petroleum exploration and development, we should consider the seismic reflection, sedimentary distribution, hydrocarbon-water relations pressure, and even the distance between wells.
