Characterizing the source of the Eastern Galicia Magnetic Anomaly (NW Spain): the role of extension in the origin of magnetization at the Central Iberian Arc

Abstract

[EN]This paper deals with the origin of the Eastern Galicia Magnetic Anomaly. We proposed that it is linked to late-Variscan Extensional processes that changed the redox conditions of the crustal melts allowing the entrance of fluids and increasing the oxigen fugacit
