MICRO-PALEONTOLOGY AND LITHOSTRATIGRAPICAL STUDY OF ILAM FORMATION IN LORESTAN PROVINCE OF IRAN (POSHTE JANGAL ANTICLINE)

Authors

Abstract

In order to undertake micropaleontological and petrological studies of Ilam formation in southwestern region of Khorramabad, a stratigraphy section on Poshte Jangal anticline has been selected. The real thickness of this section was 190 meters and mainly consisted of uniform alternations and a sequence of limestones aggregated on each other through a continuous sedimentation during mid-Turonian to pre-Campanian. The studies section showed that this formation has been laid down over Sourgah formation with a progressive boundary and covered by Gourpi formation as well with a progressive-continuous boundary. In present study, 10 types, 40 species, and two biozones of Foraminifera Planktonic have been discovered. In this study, two biozones have been observed and identified which represent the age of mid-Turonian to pre-Campanian for Ilam’s formation in this stratigraphy section, based on its fossil distribution
