The geological study presented in this thesis draws a new time-rock synopsis and stratigraphic framework for the studied succession, covering Berriasian to Aptian shallow-platform deposits in the Zagros fold and thrust belt, SW Iran. The dataset includes 19 outcrops and five subsurface wells located in the Bandar Abbas Hinterland to the East and the Dezful Embayment, Khuzestan area, to the West. Acquired data pertain to lithostratigraphy (new lithostratigraphy nomenclature), biostratigraphy (new biozonation pattern), facies interpretation, sequence stratigraphy (new sequential framework), depositional environments, platform reconstruction, chemostratigraphy (δ13C and δ18O) as palaeoenvironmental indicators, Sr-isotope analyses (numerical dating) and outcrop gamma-ray spectrometry.
