Tectonic Geomorphology Of Başkale Fault Zone, Azad Sağlam Selçuk, Meryem Düzgün

Bulletin of the Mineral Research and Exploration

Başkale Fault Zone is located between Şemdinli-Yüksekova fault zone in southeast Turkey and Guilato–Siahcheshmeh–Khoy fault system in southeast Iran. The fault zone starts from Yavuzlar town extending to Işıklar village in southwest. The BFZ is composed of three different segments which have orientations varying N75°E to N 80°E. Offset streams, fault-controlled drainage system such as Çığılsuyu stream, alluvial fans which line up parallel to the fault and contain deformation structures, fault flats, Plio-Quaternary volcanic rocks and volcanic structures, and fissure ridge travertines with formation continuing today are among morphotectonic characteristics that indicate the BFZ is active.

The Kağızman-Tuzluca Basin in East Anatolia is still poorly documented for its stratigraphy and in particular its paleofloral assemblages. In this study, the microfloras from the Kağızman-Kötek and Kömürlü areas and the macroflora from the Tuzluca area in this basin have been defined to overcome this deficiency. Sedimentary sequences of the Kağızman-Kömürlü area have been deposited in terrestrial conditions different from the sequences of the Kağızman-Kötek and Tuzluca areas, which were deposited in brackish conditions near a shallow marine environment. Paleovegetation in eastern Anatolia is represented by mixed mesophytic and coniferous forests restricted to high and middle altitudes (e.g. Pinus, …
