JAÉN / Prehnite from Carchelejo

An ophite quarry in Carchelejo, Jaén, Spain produced good Prehnite, some of which are intensely green, with spherical forms, and often associated with brilliant Augite.
The quarry is now closed, so new specimens are unlikely to be found in the future.

MÁLAGA / Blue Quartz with Magnesioriebeckite

In the Ofite quarries in the provinces of Málaga and Jaén they find these blue Quartz, whose color is due to inclusions of Magnesioriebeckite. The crystals are often doubly terminated.

MÁLAGA / Spinel

Local collectors found Spinel on Dolomite matrix. The crystal form is not excellent, but their color is not bad and the contrast with the white matrix is good. Plus they are fluorescent (red). Some minor yellow Clinohumite crystals are also present, these are fluorescent too, in this case yellow.

Azurite and Malachite

 

NMB61XXX: Lenticular Azurite crystals forming an interlaced cluster of crystals, on matrix, of a very uniform and intense electric blue color, bright, and accompanied by green Malachite crystals that provide a beautiful color contrast.
The specimen, of high quality for the locality, comes from the collection of Fermín Clemente.

Santa Flora Mine belongs to the Sierra Norte mining district of Seville, within the Ossa-Morena Zone, a Paleozoic geological domain affected by the Variscan orogeny. Mineralization is mainly hydrothermal vein-type, hosted in fractures and shear zones developed in Hercynian metamorphic and igneous rocks.
The veins are dominated by metallic sulfides, mainly of lead, zinc, and copper, with gangue minerals such as Quartz, Calcite, and Baryte. This mineralization style is typical of Variscan hydrothermal systems in the area, historically worked through small to medium-scale mining operations controlled by regional structures.

JMF14AP8: Fine, very sharp crystals of Baryte, between transparent and translucent, with good luster and sky-blue color, on a Goethite matrix.
