The Develidag volcanic zone (DVZ) is a part of the Middle Miocene-Quaternary Cappadocian Volcanic Province (CVP) in central Anatolia. The DVZ is located at the eastern side of the Plio-Quaternary Sultan-sazligi pull-apart basin, that opened along the Ecemis left-lateral strike-slip fault. Towards the South, the volcanic rocks of the DVZ overlie the Paleozoic metamorphic rocks of the Taurus range. Regional strati-graphic studies indicate that volcanic rocks of the DVZ crop Out in a similar to N-S trending rectangular-shaped exposure in the middle of which Middle Miocene andesitic rocks are found surrounded by Upper Miocene basaltic rocks. The purpose of this paper is to present basic geochemical data for the DVZ rocks and discuss possible processes of magma generation.
