BackgroundAs described by Oyan et al. (2010), the Pliocene Etrüsk volcano is one of the major volcanic centers of eastern Anatolia, just NE of Lake Van. There is a ~5-km-wide horseshoe-shaped caldera near the center of the volcano, with the Pleistocene Karniyak scoria cone about 11 km away on the SW flank near the lake. K-Ar age determinations by Oyan et al (2010) indicate that the main volcanic edifice of Etrusk was formed between 4.3 and 3.9 Ma, ending with caldera collapse. Between ~1 and 0.43 Ma, basalts erupted from the SW flank, predominantly from a ~N-S extending fissure, as well as from Karniyarik hill and a maar-shaped volcanic center (Düzgeyikçukuru). Lebedev et al. (2009) noted that the youngest dated trachybasalt from Karniyarek was 0.36 +/- 0.06 Ma.
