%X Basic magmatism in Central Spain occur sporadically during a long period of ca. 140 Ma. The scarce dataset of incompatible trace element geochemistry and initial isotopic ratios (Sr, Nd) on mantle-derived basicmagmatism shaw that subcontinental mantle in Central Spain is markedly heterogeneous. Depleted mantlecompositions are not registered and basic magmatism f1uctuate between OIB and BSE values, being crustalinvolvement (via recycling in mantle sources or by hybridization at emplacement levels) an importantcontribution ta some basic derivates.
