Abstract:

 


The Pliocene aged Tutak volcanic rocks located in the northeast of Turkey is one of the most important basaltic plateaus related to the collision in the East Anatolia. Volcanic products have basaltic compositions and they plot on alkaline-sub-alkaline division line. All of the basaltic lavas composed of olivine, pyroxene, plagioclase and opaque mineral phenocrystals and microlites, displaying intersertal, subophitic and flow textures. Fractional crystallisation and EC-RAFC (Energy-constrained assimilation, fractional crystallisation and magma recharge) models indicate that fractional crystallisation and crustal contamination play an important role in the evolution of the Tutak volcanic rocks. Lower 144Nd/143Nd and higher 87Sr/86Sr isotopic ratios and enrichment of large ion lithophile elements (LILE) and light rare earth elements (LREE) relative to high strength field elements (HFSE) of the least evolved basaltic samples indicate that the mantle source region might be enriched by melts that were derived from subducted sediments. Partial melting models generated by using rare earth element systematics calculations show that basaltic melts might have been produced by melting of a metasomatised mantle source containing both amphibole and garnet with a partial melting degree between 0.2 and 2%.
