With mantle xenoliths from Tallante (South Spain) incompatible elements and Sr-Nd isotopes record in most samples widespread enrichments produced by percolation of Na-alkaline melts (by both porous flow and open-conduit mechanisms) leading to variably vein xenoliths. On the other hand, 3 samples out of 55, containing traces of amphibole and phlogopite and characterised by relatively high SiO2 content (and high modal abundance of opx) display enrichments characterised by a completely different geochemical fingerprint.
