Cenozoic Tectono-Stratigraphic and Geodynamic Evolution of the Eastern Strike-Slip Margin of the Arabian Plate

Summary The southeastern Oman is located at the articulation of an “older” N20° E strike-slip margin in the East and a “younger” N70°E divergent margin in the South. The Eastern strike-slip margin was initiated in the Late Jurassic during the separation between the African–Arabian plate and the Indian–Madagascar–Seychelles plate ( Rabinowitz et al., 1983 ; Beurrier, 1987 ; Coffin & Rabinowitz, 1992 ; Salman & Abdula, 1995 ; Gnos et al., 1997 ; Marquer et al., 1998 ; Peters & Mercolli, 1998 ; Rodriguez et al., 2016 ). The detail architecture and the evolution of the margin remain unclear. We attempt to improve our knowledge of the area by a detail integrated field and subsurface study based on new sedimentological, paleontological and stratigraphical analysis of the Paleocene–Miocene deposits in the southeastern. Our work provides a detailed tectono-stratigraphic architecture scheme highlighting the evolution of the margin during the Cenozoic. It also provides new insights for the understanding of the relative motion between the Arabian and the Indian plates during this time.
