Lamproites (7.2-7.6 My).

Some older literature uses Cabo da Gata as location.

The apatite rich rock was used as phosphate fertiliser.

Historic and world-famous site especially for its magnificent crystals of Fluorapatite known since the eighteenth century. The species was named "Chrysolithe d'Espagne" (by Romé de L'Isle) and was also known by the names "Spargelstein" (Werner) and "Esparraguina" (in Spanish) for the resemblance of the crystals with stems of the asparagus.

The specimens were analyzed for the first time by Vauquelin (1797) classifying them as calcium phosphate. Proust found the presence of fluorine in this mineral. The crystals were also studied by the crystallographers Romé de L'Isle, Haüy, Michael Levy, Schauf Albrecht, and Heinrich Adolf Baumhauer among others, which gives us a clear idea of the importance of this historic site. A detailed account about the history of this locality can be found in Calvo (2015).

The deposit is related to post-magmatic alteration of rare volcanic (or subvolcanic) rocks of ultra-potassic composition called lamproites known historically as "Jumilitas" (through the town of Jumilla, which is the most important town near the outcrops) associated with diapiric outcrops of Keuper facies (Triassic age), diapiric movements (Miocene age) and volcanic extrusions of Upper Pliocene age.

Inside vacuoles in the altered parts of the volcanic rock, the magnificent specimens of Fluorapatite can be found together with a complex paragenesis, e.g. Pseudobrookite and the rare borate Yuanfuliite.
