Geocronología y geoquímica isotópica de yacimientos de Sn-W en el Macizo Varisco Ibérico

The Iberian Variscan Massif, representing the southernmost branch of the European Variscan belt, is the host for a significant economic potential for different types of Sn and W ores. Here, the Sn-(Ta-Li) mineralization occurs disseminated in pegmatites and granite cupolas or associated with peri-gr...
