The Kizilkaya ignimbrite — an unusual low-aspect-ratio ignimbrite from Cappadocia, central Turkey

Paleoseismological Three Dimensional Virtual Photography Method; A Case Study: Bağlarkayası-2010 Trench, Tuz Gölü Fault Zone, Central Anatolia, Turkey

“…The age of Kızılkaya Ignimbrites was determined by various researchers using different methods. For example, employing K/ AR method, while Innocenti et al (1975) obtained 5.4  1.1 million years, Besang et al (1977) 5.4  1.1 million years, and Schumacher and Schumacher (1996) 4.3  0.2 and 4.5  0.2 million years of age for Kızılkaya Ignimbrites. On the other hand, Aydar et al (2012) obtained 5.19  0.07 and 5.11  0.37 million years of age employing the method of Ar/Ar.…”

Geology, mineralogy, geochemistry, and depositional environment of a Late Miocene/Pliocene fluviolacustrine succession, Cappadocian Volcanic Province, central Anatolia, Turkey

“…Consistent with this worldwide pattern, the mineralogy, petrography, and geochemistry of volcanic and pyroclastic rocks (especially ignimbrites) and the tectonics of the Cappadocian Volcanic Province (CVP) have been studied by many researchers (Beekman, 1966;Pasquaré, 1968;Innocenti et al, 1975;Pasquaré et al, 1988;Temel, 1992;Göncüoğlu and Toprak, 1992;Le Pennec et al, 1994, 2005Schumacher and Mues-Schumacher, 1996;Toprak, 1996Toprak, , 1998Schumacher and Schumacher, 1997;Temel et al, 1998;Dirik, 2001;ViereckGoette et al, 2010). In this region, the volcano-sedimentary rocks and associated palaeosols and calcretes have received little attention (Le Pennec et al, 2005;Gürel and Kadir, 2006Gürel and Yıldız, 2007;Gürel, 2009;Yavuz-Işık and Toprak, 2010;Kadir et al, 2013).…”

“…According to Le Pennec et al (1994) the source region of the Kzlkaya ignimbrite is located in the southwestern part of the Derinkuyu plain ( Figure 3a). On the other hand, Schumacher and Mues-Schumacher (1996) suggested, based on an isopach map of the Kzlkaya plinian fall-out layer and on lateral variations of welding in the Kzlkaya ignimbrite (Figure 3b), that the source area is situated somewhere between Yarhisar and Edikli in the Misli plain. However, on the basis of gravity data, remote sensing data and digital elevation models Froger et al (1998) have identified two major caldera complexes and supported the proposed source areas of Le Pennec et al (1994): (1) Nevs¸ehir-Acgöl caldera complex as the source of Kavak and Zelve ignimbrites and (2) Derinkuyu caldera complex, located between the Erdas Dag massif and the Ç iftlik depression, as the source region for the Sarmaden, Cemilköy, Gördeles and Kzlkaya ignimbrites.…”

“…The Derinkuyu caldera complex is also the possible source region for the upper ignimbrite in the study area. The areal distribution of the Kzlkaya ignimbrite and location of the assumed source area of Edikli in the Misli Plain (from Schumacher and Mues-Schumacher 1996). The approximate ignimbrite thickness is indicated.…”
