ABSTRACT
The Minjur Formation crops out along the eastern rim of the Arabian shield and consists of alternating sandstone and shales with minor carbonates. Informally subdivided into lower and upper units, the Minjur Formation records depositional environments ranging from alluvial to marginal marine with tidally influenced channels. The stacking patterns reflect delta or shoreline progradation and retrogradation, recording an overall coarsening upward character. In outcrop, the Minjur Formation was dated as Norian by conodonts near the base. In the subsurface, palynology has established a fourfold biostratigraphic subdivision extending from latest Carnian–early Norian to latest Rhaetian–Pliensbachian (Triassic–Early Jurassic). This study improves...
