Abstract:

Two typical transfer zones,the lateral uplift and the strike slope,are common in rifted-basins.Large-scale sandbodies of fan delta or turbidite fan are generally developed in the corresponding down throw blocks.The controlling mechanism of these transfer zones on sandbodies is the differential palaeotopography caused by syndepositional faulting,especially the convergence and guidance of drainage systems by the palaeotopographic low on the down throw blocks in the transfer zone.Apart from that,the antithetic parallel transfer zone,developed at the large lengthways uplift belt in the central of rifted-basins,usually forms fault-troughs serving as axial channels for sediment transportation.

Key words: transfer zone, extensional structure system, reservoir prediction, rifted basin
