The delta deposits from the Zhuhai Formation in the Zhu-1 depression of the Zhujiangkou Basin

Twelve lithofacies including the sandstone and conglomerate facies with massive bedding,sandstone facies with trough cross-bedding and sandstone facies with parallel bedding are recognized in the Zhuhai Formation on the basis of lithofacies,well logs and seismic reflection profiles of the delta deposits from the Zhuhai Formation in the Zhu-1 depression of the Zhujiangkou Basin.The delta deposits take diverse forms:composite boxes or composite funnels for well logs,and wedge-shaped,sigmoidal and mound for seismic reflection configurations.
