Cr-diopside lherzolite and Al-augite wehrlite mantle xenolith types were described.
Former type is mostly mantle residue; while the latter one is deep mantle cumulate.
Peculiar Al-spinel micropods described for the first time from the wehrlite xenoliths.
Thermal and oxidation states beneath the Arabian Shield are inferred.
Genesis of Al-spinel micropods is discussed and compared with ophiolitic chromitite.
