However, as the composition of the volcanic rocks may be the result of several combined magmatic processes, it is necessary to identify them before any attempt to their quantitative modelling. On the other hand, the information provided by partial melting modelling is limited to the final composition of the mantle source whereas some characteristics, like the presence of minor phases, can be cloaked if those minerals have not remained in the residue. A good example to illustrate the problems of this method is found in the Quaternary primitive basaltic rocks of La Garrotxa (ME Volcanic Region of Spain) which, according to a combined study o f trace element modelling and Sr-Nd-Pb isotopic ratios, can be interpreted as the result of the melting of a previously enriched lithospheric source which has been subsequently pervaded by basaltic melts derived from a common European sublithospheric reservoir.spajournal articlehttp://www.sociedadgeologica.es/publicaciones_geotemas.htmlopen access551.21Mantle lithosphereMantle metasomatismPartial meltingTrace element modellingNE Volcanic Province of SpainGeodinámica2507 Geofísica
