摘要：

Analysis of seismic lines coupled with gravity interpretation in the western Gulf of Oman, shows that the rootless Cretaceous ophiolite nappes are bounded to the north by the deep arcuate Sohar Basin. Two phases of sedimentary infill are clearly identified; from late Campanian to Miocene and from Miocene to Quaternary. The Sohar Basin is separated from the oceanic domain by a continental axis interpreted as the NW seaward prolongation of the Saih-Hatat metamorphic unit. We assume that creation of the Sohar Basin resulted from a late-obduction uplift of the Saih-Hatat axis followed by the re-working of the basal thrust during a later Neogene compressive event.
