Petrogenesis of Mediterranean lamproites and associated rocks: The role of overprinted metasomatic events in the post-collisional lithospheric upper mantle
High-MgO lamproite and lamproite-like (ie lamprophyric) ultrapotassic rocks are recurrent in
the Mediterranean and surrounding regions. They are associated in space and time with …
