Lamproites which outcrop a few hundred meters SW of the village of Los Nietos, in Diputación de La Aljorra, term City of Cartagena (Murcia). The intrusion is 600 m long and 350 m wide, and has intruded calcareous shists, deformed and fractured by the intrusion. By analogy with other lamproites in this area, the intrusion is of Neogene age (Pellicer, 1973).

The inner zone of the intrusion consists of a compact rock, with olivine phenocrysts that can reach a size of several millimeters, but usually are strongly altered to serpentine.
According to Pellicer (1973), olivine has a reduced content of forsterite, which indicates a fairly evolved intrusion. In the compact rock, there are also phenocrysts of diopside, sanidine and phlogopite. At the border of the intrusion, the lamproites becomes enriched in voids. The vesicles can reach ... metres in length, and contain various mineral species.
