Abstract
Early to Middle Miocene andesite-dacite porphyries are well exposed to the Pertek area of Tunceli, Eastern Anatolia, and represent an example of adakite-like magma generation in Eastern Anatolia (postsubductional) collisional setting. Mineral associations in these porphyries are composed of plagioclase (oligoclase-andesine-labradorite), amphibole (pargasite-ferropargasite), biotite, rare quartz, K-feldspar, and minor Fe-Ti oxides. Geochemically they are high-K calc-alkaline in nature and characterized by high SiO2 (>62 wt.%), Al2 O3 (mostly >16 wt.%), Na2 O/K2 O ratio (1.3–1.7), and Sr (generally >400 ppm) contents. Volcanic rocks display depletion in HFSEs, Nb, Ta, and Ti, and slight negative Eu anomaly; have low HREEs, Y (
