Abstract
Las rocas lamproíticas del Sureste de España constituyen dentro del vulcanismo neógeno uno de los exponentes geológicos más
destacados de la actividad magmática producida en el sureste peninsular durante el Mioceno (Tortoniense-Mesiniense). Estas rocas
contienen información primordial sobre la composición del manto
terrestre siendo, por tanto, muy importante su conservación. Además, las rocas lamproítas de esta provincia volcánica, son sin duda
una oportunidad única para estudiar las composiciones magmáticas de fluidos profundos, constituyendo un campo volcánico de interés internacional por su rareza y por su mineralogía. En este trabajo
preliminar pretendemos recopilar y presentar las paragénesis de los
mismos, así como los minerales cristalizados en las vacuolas durante los procesos de desgasificación y enfriamiento de estas rocas
Lamproite rocks of the southeastern Spain are one of the highest expressions of the Neogene vulcanism concerning magmatic activity produced during the Miocene (Tortonian- Messinian). These rocks provide us with primary data about the terrestrial mantle, hence, the importance of their preservation and further study. Lamproite rocks of this volcanic province are undoubtedly a unique opportunity to study the magmatic compositions of deep fluids, constituting a volcanic field of international interest due to its rarity and its mineralogy. In this preliminary paper, we attempt to gather and explain such unique lamproites’ paragenesis, as well as to analyse those minerals crystallized in the vacuoles during the degassing and cooling processes of these rocks
