%X The Craters of Meke Lake and Ac£¿g£¿l 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 Ac£¿g£¿l. Volcanics formed by the main mineralogical composition plagioclases (Meke An56-80; Ac£¿g£¿l An46-68), pyroxene (Meke Wo37-51, Ac£¿g£¿l 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 Ac£¿g£¿l are characterized by the continental arc setting and the calc-alkaline to alkaline in nature. The petrographic, geochemical and geothermobarometric studies indicate that Ac£¿g£¿l and Meke volcanics crystallized under respectively 1093-1107 ¡ãC-0.9-1 kb and 1133-1141 ¡ãC - 4.7-5.3 kb conditions. Meke and Ac£¿g£¿l are characterized by the continental arc setting and the calc-alkaline in nat¨¹re
