Magmatismo alcalino tardicadomiense en la zona de Ossa Morena (Macizo Ibérico): Cartografía, petrografía y geoquímica preliminar del Macizo de Almendral

Abstract

The Almendral massif is located in the north-western branch of the Olivenza-Monesterio antiform (Ossa Morena Zone, Iberian Massif, Spain). The pluton is composed by gabbros, sienites and alkaline granites which define an alkaline/transitional association. This magmatism marks the transition between the Cadomian orogenic regime and the Pre-Hercynian intracontinental rift for this sector
