Tectonostratigraphy of the Arabian Plate

Summary The Arabian Plate exhibits a complex geological history shaped by both long-term tectonic stability and episodic deformation. This study presents an integrated tectonostratigraphic analysis combining new outcrop and core data with advanced sequence stratigraphic techniques. Field investigations across key localities and core analysis from subsurface wells were used alongside seismic and well-log data to construct regionally correlated stratigraphic frameworks. The interior of the Arabian Plate is defined by a stable cratonic setting, with localized tectonic reactivation near plate boundaries such as the Zagros Fold-Thrust Belt and Red Sea Rift. Jurassic and Cretaceous successions show significant lateral facies variability, marked by carbonate build-ups and intrashelf basin development influenced by both tectonic activity and eustatic sea-level changes. Sequence stratigraphic interpretation reveals regionally persistent maximum flooding surfaces and major discontinuities linked to tectonic events. A key finding is the dominant role of salt tectonics, particularly the mobilization of the Hormuz Salt, which has formed over 200 diapirs. These structures have significantly influenced sediment dispersal, stratigraphic architecture, reservoir compartmentalization, and hydrocarbon trap formation. This research enhances our understanding of the Arabian Plate’s geological evolution and provides valuable insights for hydrocarbon exploration and geohazard assessments in the region.
