The range of coeval potassic magmatism in the Isparta Angle, SW Turkey is a natural laboratory to elucidate the mantle beneath the region.
The Kayıköy leucite-ankaratrites represent most silica-deficient mafic potassic lavas within the Inner Isparta Angle volcanic province.
The major, trace element and isotope compositions of the Kayıköy leucite-ankaratrites show affinities to kamafugites and carbonatites.
Mixing of both carbonate and silicate melts from asthenosphere produced carbonated phonolitic melts.
The carbonate-bearing phonolitic melts react with peridotitic wall rock to produce wherlitic metasomes.
The leucite-ankaratrites are derived from partial melting of the wherlitic mantle metasomes.
