Résumé
The ophiolitic complex of Zdraljica (Central Serbia) belongs to the Eastern Branch of the Vardar suture zone. It was emp'aced during the Upper Jurassic. The complex consists predominately of a MORB/VAB-like tholeiitic suite, represented mostly by gabbros and diabases. Small occurrences of cummulitic peridotites, basalts and plagiogranites also appear. The tholeiitic suite is intruded by calc-alkaline intermediate and acid magmas. Geochemical data suggest that the ZOC tholeiitic rocks originated by partial melting of a spinel-lherzolite source. Non-modal batch melting modeling indicates 10 to 15 % of partial melting of such a source. The magmas were later modified by fractional crystallization. One-step major element modeling requires 40% (F=0.60) of fractional crystallization of a mineral assemblage: PI52 gCpxi2 5OI26 iTtn2 9Ap4.4Mgt1.0- The model is supported by the variation patterns of most trace elements.
