Abstract: The K-rich metavolcanites of Kadınhanı (Konya) have undergone low grade metamorphism characterized by sericitization, chloritization and albitization. The rocks are transitional between alkaline and tholeiitic, trachyandesite in composition and havewithin-plate lava characteristics. They are extremely K-rich (6.5-11.1 wt. % K2O) and show also strong enrichments in LILE andLREE, implying possibly an enriched source. In addition, depletion in Nb indicates the presence of a subduction component in magmagenesis. These enrichments probably occurred in the source region prior to magma generation. The parental magma of the rocks wasformed in an extensional regime and derived from subcontinental lithosphere involving a small amount of subduction component. Their mantle source was geochemically capable of supplying the K-rich material.
