AB Basic magmatism in Central Spain occur sporadically during a long period of ca. 140 Ma. The scarce data set of incompatible trace element geochemistry and initial isotopic ratios (Sr, Nd) on mantle-derived basic magmatism show that subcontinental mantle in Central Spain is markedly heterogeneous. Depleted mantle compositions are not registered and basic magmatism fluctuate between OIB and BSE values, being crustal involvement (via recycling in mantle sources or by hybridization at emplacement levels) an important contribution to some basic derivates
