The early Palaeozoic represents an important geological period characterized by a series of major climatic, biological and geodynamic events. The Zagros Basin (SW Iran) is a key area for the study of this time interval, due to the widespread and well-exposed Cambrian-Ordovician successions. The Tang-e- Ilbeyk section (293 m thick), characterized by the superimposition of carbonate- siliciclastic lithological units, provided useful data for palaeoenvironmental and palaeoclimatic reconstructions and new constraints for the lower Palaeozoic palaeogeography of Middle East.
