Abstract

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 shaw that subcontinental mantle in Central Spain is markedly heterogeneous. Depleted mantle
compositions are not registered and basic magmatism f1uctuate between OIB and BSE values, being crustal
involvement (via recycling in mantle sources or by hybridization at emplacement levels) an important
contribution ta some basic derivates.
