Geochemical variability among stratiform chromitites and ultramafic rocks from Western Makran, South Iran

Geochemistry of basaltic blueschists from the Deyader Metamorphic Complex (Makran Accretionary Prism, SE Iran): New constraints for magma generation in the Makran sector of the Neo-Tethys

“…The Sorkhband and Rudan ophiolites crop out in the western part of the North Makran within the shear zone between the Coloured Mélange and the Bajgan Complex (McCall, 2002;Delavari et al, 2016). They largely consist of peridotites formed in a supra-subduction zone setting (Moghadam et al, 2022) The Coloured Mélange Complex is composed of metric-to decametric-thick tectonic slices and was formed in Cretaceous-Paleocene times (McCall and Kidd, 1982;McCall, 2002;Burg, 2018;Esmaeili et al, 2020). This mélange incorporates a great variety of volcanic and meta-volcanic rock-types formed in both the subducting oceanic plate and the upper plate (Saccani et al, 2018;Esmaeili et al, 2020Esmaeili et al, , 2021.…”
