REE, Y, Rb, Sr, Cs, Ba, Pb, Th, U, Zr, Hf, and Sn are reported for a basalt, low-Si andesite, andesite, high-K andesite, dacite and rhyolite from the calc-alkaline volcanic belt of Calimani-Harghita Mountains (Rumenian Carpathians). The basalt, low-Si andesite and andesite show identical chondrite-normalized REE patterns with fractionated light REE (La-Sa) and unfractionated heavy REE (Gd-Yb). The dacite shows similar pattern but lower ΣREE. The high-K andesite and rhyolite have a distinctively different REE pattern strongly fractionated for both light and heavy REE. These differences point to different genetical mechanism for the high-K andesite-rhyolite and basalt-low-Si andesite-andesite-dacite magmas. The high-K andesite and rhyolite magmas are believed to represent primary melts of an undergoing oceanic slab; the basalt, low-Si andesite, andesite and dacite magmas are considered to be produced by partial melting of garnet pyroxenite bodies derived by reaction between the primary melts of the undergoing oceanic slab and the peridotitic mantle overlying the Benioff zone.
