Özet

In this study we investigate the spinel and whole rock chemistry of ultramafic rocks in the Divrigi-Sivas region hosting one of the largest ophiolite suites in Turkey, which were emplaced following the convergence between the African and Eurasian plates in the Late Cretaceous. The ophiolitic melange (Gunes Ophiolite) in Divrigi is composed of ultramafic rocks, amphibolites, sub-ophiolitic metamorphic rocks and calc-silicates. The ultramafic rock section is made up of serpentinized wehrlites overlain by irregular segregations of pyroxenite levels.
