Figure 12: Paleofacies of the earliest Cretaceous spanning the deposition of the Yamama, Minagish, Habshan, and Rayda formations, and their regional equivalents [MFS intra-K20 to intra-K40]. Relatively continuous sedimentation took place in Oman but most other parts of the Arabian Plate were affected by a late Valangian unconformity. Sediments were deposited on open platforms and within intrashelf basins of the Arabian Plate. With information from: Béchennec et al. (1989); Ellis et al.
