Classification and Generation of the Enclaves in Karapınar-Karacadağ Volcanic Rocks (Central Anatolia)

Karapınar-Karacadağ Volcanic Rocks (KKVR) have very complex magmatic history and outcropped the southwestern part of Cappadocia Province (Central Anatolia). Here we present petrography whole-rock chemistry enclave-bearing rocks to constrain their source evolution history. These petrographic observation geochemical data reveal that enclaves in volcanic are magma mixing/mingling (MME), segregation (MSE), xenoliths. discriminated these into eight different types according mineral composition textural features. The (Type 1, 7, 8) mixing products coeval more felsic mafic magmas. They show hypocrystalline porphyritic, holocrystalline granular, intergranular textures, rich minerals, characteristic features such as quenched amphibole, bladed biotite, ocelli-quartz, sieved cellular plagioclases. In andesites they range from basalt andesite composition. However, basalts, basaltic 2, 4, 5, 6), which observed almost all KKVRs, cognate xenolith because plucking parts chamber. granular texture. contained andesitic host hornblende gabbro pyroxene composition, whereas dunite, lherzolite, xenolithic 3) basalts quartz, plagioclase, amphibole xenocrysts. Major oxides trace element studied indicate MSEs primitive than rocks, (MME-MSE) accordance with hosts. According observations propose fractional crystallization, assimilation processes a key role KKVRs enclaves.
