Siyamak Moradi, N. Kalantari, A. Charchi
Zagros mountain range (ZMR) contains the most karstic carbonate formations in Iran. Because of the broad expansion of folded and fractured carbonate rocks, well-developed karstic features occur in the southwest of ZMR. The study area, which occupied 794 km2, is located in the ZMR of Khuzestan province and mostly is covered with Asmari Formation. In the study area, the most important karstic formations are the Asmari and the Ilam-Sarvak Formations and the two examples of karst plains (Polje) were created through tectonic activities and dissolution process of water in the Asmari Formation. Geological setting and climate condition are the most important factors of karst development in the study area. The region has a wide variety of developed karstic features. Accordingly, the purpose of this paper is to identify and introduce karst features of the study area including polje, karst valley, doline, waterfall, ponor, lapiez, rain pit, cave and karst spring.
