Petrography and Geochemistry of the Ulukışla-Çamardı (Niğde) Magmatites

Abstract: Ulukışla-Çamardı magmatics overing a alarge area around Uiukışla-Çamardı are bounded by the Niğdemassif on the north, the Ecemiş corridor on the east, Bolkarlar on the south, and the Tuzgölü basin on the w§st.North-dipping a subduction zone and resulting magmatie arc developed above an oceanic crust during the Upper Cretaceous in the region, Magmatics are made up of intrusive, subvoleanie, and volcanic rocks. Morphology of volcanicsappears as lava flow, pillow lawa, flow breccia, dike and tuff-mfftes, F^om place to place volcanics alternats with sedimentary rocks.Magmatic rocks consist of diorite-gabbro, monzonite, basalt-andesite» laüte basalMatite andésite, laute, and trachyte. Chemical composition of the rocks indicate that they resulted from magmatic arc and partly influenced by themantle.
