In the Mediterranean area, four major lamproitic provinces with uniform geological, geochemical, and petrographic characteristics are recognized: Spain, Italy, Balkans, and Turkey. Mediterranean lamproites are SiO₂-rich lamproites, characterized low CaO, Al₂O₃, and Na₂O, and high K₂O/Al₂O₃ and Mg-number. They are enriched by in large ion lithophile elements relative to high field strength elements and in Pb, and show depletion in Ti, Nb, and Ta. The Mediterranean lamproites are characterized by a wide range of ⁸⁷Sr/⁸⁶ and ¹⁴³Nd/¹⁴⁴Sr_i Nd_i. Both...
