Abstract：Based on external characteristics,the inner structure and the plain distribution of seismic reflection,as well as the eustatic sea level changes,the sedimentary genesis of NE-trending banded K22 shelf sand ridges of the Zhujiang Formation in Huizhou sag,Pearl River Mouth River Basin, was studied with the sequence stratigraphy theory and method. The results show that the K22 shelf sand ridges were considered to be redeposited products primarily formed during the forced regression. The K22 shelf sand ridges were preferentially present on high paleo-tectonic locations with the former delta as provenance. The diverse depositional hydro-dynamics mainly included tide currents and wave effects,besides,coastal currents also contribute to the shape of the K22 shelf sand ridges. The sand ridges were preserved benefiting from the subsequent fast transgression,which were then wrapped in the marine mud and would be available to form lithological traps.
