Los granitos con cordierita tienen valores intermedios (entre 9,8 y 10,50/00), sugiriendo la posibilidad de ser el resultado de la asimilación de nebulitas por el magma que origina los granitos biotíticos}, abstract = {The relationships of oxygen isotopic of various types of granites and migmatites (cordierite nebulite) in western regions of the Central Iberian Massif, Spain, have been determined.
