Süphan is a stratovolcano in eastern Turkey, rising some 4,050 m above sea level. The oldest (<2 million years) silicic units are overlain by basaltic to trachytic lava flows extending several kilometers around the volcano. This eruptive phase dates from ~ 0.5 – 0.2 million years ago and is responsible for the construction of the main stratocone. Numerous lava domes and pyroclastic cones are found on flanks of the volcano and the most recent product of (phreatomagmatic) volcanism includes a rhyolitic maar. Süphan is noted for having produced an exceptionally wide range of erupted magma types from a series of closely spaced vents. CRITMAG-funded research is aiming to unravel the relative importance of magma crystallization and mixing processes in generating this compositional diversity.
