The tectonite peridotites are most formed by clinopyroxene harzburgites. These harzburgites characterized by protogranular, porphyroclastic and transformation textures, and composed of olivine (with kink band), orthopyroxene (with wavy extinction and exsolution clinopyroxene), spinel (like Holly – Leaf and shaped) and less than 10% of clinopyroxene. Two stages of alteration occur in these rocks, including static and dynamic. These peridotites are partial melting residual of spinel lherzolites. The Khoy tectonite peridotites show the U-form pattern in the REEs. These patterns are probably related to the partial melting procedures and the process following the partial melting such as influence of felsic magmas after emplacement of ophiolites.
