The neotectomic regime of the eastern Turkey has caused intensive volcanism and different kinds of terrestrial basin, such as intermountain (Mus, Erzurum, Tekman, and Pasinler) and pull-apart (Igdir-Kagizman) basins. The study is based on basin evolution and depositional history of the Igdir Kagizman basin, which was developed under different climatic and tectonic regimes through the Neogene period (? Late Oligocene / early Miocene to late Pliocene). From bottom to top, the terrestrial deposits were divided into four episodes represented by siliciclastic lake (delta-dominated), carbonate lake (marls-peals), fluvial (low-grade rivers and anastomosing streams) and evaporite lake (halite-gypsum), respectively. These depositional episodes are also reflection of the paleoclimatic changes from humid (deltaic: Episodes I-II), humid-arid (carbonate lake-fluvial: Episodes III-IV) and highly arid (evaporite lake and saline pan: Episode V). The basin tectonically became active during deposition of Episodes I-II, whereas Episodes III-V reflect moderately tectonism and environmental quiescence.
