Estimación de la composición del manto subcontinental en el centro de España a partir de los materiales básicos hercínicos y post-hercínicos del Sistema Central Español

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.

Sumario: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.
