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.
