Petrology and Geochemistry of Ophiolitic Pyroxenite in the Eastern Desert of Egypt: Genesis of Ultramafic Cumulates and Implications for Neoproterozoic Supra‐Subduction Seafloor Metamorphism

Abstract We describe and compare two outcrops of pyroxenite associated with Neoproterozoic ophiolite sequences in the Eastern Desert of Egypt: small masses in the Abu Samuki area of the North Eastern Desert and large belts in the Wadi El‐Mireiwa area of the South Eastern Desert. This study presents...
