| 摘 要： | This paper mainly discusses the origin and deposhional features of fan-deltas and braid deltas. Fan-del-tas are storm discharge-dominated, while braid deltas are usually flashy flood-dominated. The two types ofdelta, like common deltas, were reworked by marine processes. Delta systems are classified into nine deltatypes on the basis of the subaerial depositional processes and the nature of marine reworking. Fan-deltas and braid deltas are of great significance for petroleum exploration. In divergent-marginforeland and intraplate rift-subsided basin settings fan-deltas often form combination traps for petroleum ac-cumulation.

| Abstract: | Abstract This paper mainly discusses the origin and depositional features of fan-deltas and braid deltas. Fan-deltas are storm discharge-dominated, while braid deltas are usually flashy flood-dominated. The two types of delta, like common deltas, were reworked by marine processes. Delta systems are classified into nine delta types on the.basis of. the subaerial depositional processes and the nature of marine reworking. Fan- deltas and braid deltas are of great significance for petroleum exploration. In divergent- margin foreland and intraplate rift-subsided basin settings fan-deltas often form combination traps for petroleum accumulation. |
