Ar-40/Ar-39 geochronology, elemental and Sr-Nd-Pb isotope geochemistry of the Neogene bimodal volcanism in the Yilkselen area, NW Konya (Central Anatolia, Turkey)

摘要

Bimodal volcanic suites occur in both orogenic and anorogenic geotectonic settings. Although their formation can be attributed to either fractional crystallization from basaltic parents to felsic derivatives or partial melting of different sources, the origin of bimodal suites is still unclear. By reporting mineral chemistry, Ar-40/Ar-39 geochronology, elemental and Sr-Nd-Pb isotope geochemistry data, this study aims to investigate the genesis of bimodal basalt-dacite association from the Ytikselen area located on the northern end of the Sulutas Volcanic Complex (Konya, Central Anatolia).
