dc.description.abstractMt. Nemrut volcano, situated at the west of Lake Van, is one of the historically active volcanoes of the Eastern Anatolia. It has an 8.5 x 7 km diameter summit caldera. Volcanic activity of Mt. Nemrut started similar to 1 Ma ago; the most recent eruptions were in 1441, 1597 and 1692 A.D. Among the Eastern Anatolian volcanoes, Mt. Nemrut is the most hazardous volcano for its vicinity. Present day volcanic activity is represented by intra-caldera hydrothermal and fumarolic output and low-level volcano-seismic events. Geological evolution and chronostratigraphy of the volcano is subdivided in three stages: pre-caldera, syn-caldera and post-caldera stages. Pre-caldera products are dominated by felsic lava flows and domes. Trachytic Nemrut and Kantasi pyroclastics represent the caldera forming activity, of which sequences are composed of fallout units and ignimbrite flows. Both Nemrut and Kantasi ignimbrite units are low-aspect ratio ignimbrites, they are generally densely welded and present columnar jointed outcrops locally. Extent of Nemrut ignimbrite (volume: 32.6 km(3)) is greater than the Kantasi ignimbrite (volume: 3.8 km(3)). Post-caldera activity of the volcano is marked by peralkaline rhyolitic (comendite) intra-caldera lava flows and explosive hydrovolcanic activities. Historical activity of the volcano is represented by bimodal basaltic-rhyolitic effusive activity along Nemrut rift zone. (c) 2012 Elsevier B.V. All rights reserved.
