The Craters of Meke Lake and Acigol are located in the district of Konya Province border and 6 km southeast of Karapinar. Compared with petrographical signatures, craters formed during the final stage of volcanism that effective in Plio-Quaternary comprise basalt-andesite and andesitic rocks and are found around the Meke crater, whilst the andesite and trachyandesite lithologies have been observed in Acigol. Volcanics formed by the main mineralogical composition plagioclases (Meke An56-80; Acigol An46-68), pyroxene (Meke Wo37-51, Acigol Wo40-48), amphibole and biotite are observed as mafic components. In Meke volcanics, these mafic components are accompanied by olivines (Fo70-85). The major element oxides of the rocks outcropping in the region show values the values of 51.32-64.88% SiO2, 1.16-3.09 K2O%, 2.39-3.92% Na2O, MgO 1.2-3.39%, 14.24-17.85% Al2O3, 0.18-0.35% P2O5, 5.59-9.46 % CaO, 0.09 to 0.15 % MnO and the 5.17 to 10.21 % Fe2O3. The Harker-type variation diagrams suggested that more basic characters of major oxides are observed in the rocks cropping out around the Meke Lake. MORB-normalized trace element patterns reflect strongly LILE enrichment and slightly HFSE depletion. The petrographic and geochemical studies indicate that the volcanic rocks of Meke and Acigol are characterized by the continental arc setting and the calc-alkaline to alkaline in nature. The petrographic, geochemical and geothermobarometric studies indicate that Acigol and Meke volcanics crystallized under respectively 1093-1107 degrees C-0.9-1 kb and 1133-1141 degrees C -4.7-5.3 kb conditions. Meke and Acigol are characterized by the continental arc setting and the calc-alkaline in nature.
