Biostratigraphy and lithology of the Upper Cretaceous and Paleogene of the Eastern Mediterranean region
An upper Campanian to Upper Oligocene stratigraphic succession from six deep exploration wells in the Palmiridae area of Syria has been examined. The biostratigraphical, lithological and palaeocological results were obtained from drill cutting collected from six exploration wells (Jihar-1 to 6), and from two cored intervals (Jihar-3 well: 842.5-852 m and 1604-1613 m intervals). Samples were collected every 10 to 20 m. Most of the sedimentary succession contain rich and well to moderately preserved planktonic foraminiferal assemblages that enable successful age determination. The only exception is the lowermost Paleocene deposits, which contain very rare and poorly preserved foraminiferal fauna. Lithological characteristic and microfossil content indicate deep water deposition from late Campanian to early Oligocene in upper bathial to outer shelf environments. Late Oligocene sedimentation took place in middle to inner shelf environments. The overlying lower Miocene deposits contain sporadic marine microfossils and have transitional to continental lithologic characteristics indicative of a regression. The combined observations of lithology with the diversity and composition of planktonic foraminifera assemblages indicate that the Palmyridae area in Syria was a part of an Neotethys Ocean with tropical to subtropical climate from Late Campanian to the end of Eocene with deposition in deep sea environments (upper bathial to outer shelf). On the other hand, Oligocene deposits and their and microfossil content suggest temperate to warm climate conditions and sedimentation in middle to inner shelf environments. These data enabled correlation with wider Mediterranean area. Very similar planktonic foraminiferal assemblage is documented from deep exploration wells from Adriatic Sea.
