Multistage evolution of the Aladağ mantle peridotites (S-Turkey): Processes of partial melting and melt-peridotite interaction in Mid-Ocean Ridge and Subduction Zones

The Aladağ ophiolite is located in the eastern Taurides, north of the city of Adana, southern Turkey and, from bottom to top, is composed of mantle peridotites, ultramafic-mafic cumulates, isotropic (massive) gabbro and diabase dykes. Mantle peridotites are represented by varying degrees of serpentinized dunite, harzburgite and lherzolite. We studied 100 lherzolite, harzburgite and dunite samples representing the entire Aladağ ophiolite mantle. Whole rock major and trace element analysis were performed for all samples, and mineral chemistry analysis were carried out on selected mineral phases.
