Abstract

The Plio-Quaternary associated with the Karapınar-Karacadağ Volcanic Complex (Konya-Central Anatolia) involves dacitic-andesitic domes/flows and basaltic lava flows, and their pyroclastic equivalents (e.g., base surges, ash-block flows, scoria and ash falls). The present study deals with examining the new mineral chemistry and textural investigations concerning the Karapınar mildly alkaline to calc-alkaline basalts and Karacadağ calc-alkaline intermediate rocks predominant in Central Anatolia. Application of amphibole thermobarometry and clinopyroxene-liquid thermobarometry to the Karacadağ andesites has yielded temperature estimates in the range of 855–1198 °C and pressure estimates of a range of 1.34–5.95 kbar, indicating the presence of a magma chamber lying at the middle-upper crust for intermediate unit. Temperature and pressure estimate’s as drawn from pyroxene, related to the Karapınar basalts are in the range of 1173–1251 °C and 8.9–12.2 kbar, highlighting persistence of crystallization at the crust base level. Some of the andesites, particularly the enclave bearing andesites, enclose spongy cellular, fine-coarse sieved, oscillatory and inverse zoned plagioclase, standing as the evidence of open system process. Besides, the Karapınar basalts include abundant quartz and biotite xenocrysts. There is no physical contact between the Karacadağ andesites and the Karapınar basalts surrounding the area, but the relating geochemical and textural properties appear to indicate that the Quaternary Karapınar basalts prove to be evidently assimilated from Pliocene associated with the Karacadağ andesites.
