Abstract

Permian–Triassic boundary sections in Iran belong to the best exposures of this important time interval worldwide and work as a standard for the transition beds in the Central Tethyan Realm. Increasing interest in these sections helps to solve a number of problems such as differences in lithostratigraphy, ammonoid and conodont biostratigraphy and different interpretations of the depositional environment. In this research, Ali Bashi Mountains sections are compared together and with transcaucasus sections and obstacles for a high resolution correlation are discussed. Moreover, objections about continuity of the Late Permian successions of Ali Bashi Mountains are investigated and appropriate responses are presented to them.
