Spinel-lherzolite xenoliths from Jabal al-Qiranah basalts central Jordan

الملخص EN

Spinel-lherzolite xenoliths Were found in basaltic rocks of Jabal Al-Qiranah Cone, Central Jordan.

The xenoliths consist of forsterite, enstatite, chrome diopside and spinel.

This is the first reported oc- currence of xenolith-bearing basaltic rocks in this area.

Their mineral assemblages, chemistry, textures, and major element abundances in- dicate that they were derived and equilibrated under upper-mantle conditions Within a temperature range from 1050 to 1210'C.

The presc sure as indicated through the stability field of spinel-Iherzolite, is ap- proximately that equivalent to a depth of about 70 km.
