ABSTRACT: In this research, a review
was done on Permo-Triassic deposits
in Central Iran including Abadeh, Hambast, and Elika formations. Following an
overview about the circumstances of Central Iran Basin during Permotriassic
time interval, the respective formations are introduced, and then, history of
paleontology studies on these deposits will be depicted. Through analysis and
comparison of previous studies, the following ages were estimated for the
aforementioned formations: Early Dzhulfian for Abadeh Formation, Late
Dzhulfian-Dorashamian for Hambast Formation, and Early Triassic (Scythian) for
Elika Formation. Also, Permotriassic boundary in Central Iran is continuous,
bearing the proposed sedimentation and fossil content. It is noteworthy that
due to volcanic events at the boundary of these deposits in Central Iran, one
might infer that occurrence of the aforementioned activities has been among the
major causes of the respective extinction.
