Cantera La Juanona, Antequera, Málaga, Andalucía, España
Well-known and classical Spanish locality for blue quartz crystals, coloured by inclusions of blue amphibole (presumably magnesioriebeckite, although riebeckite and "sodic-ferrogedrite" have been also reported). There is another assumption which considers that the bluish colour is produced by aerinite needles as a consequence of the associated hydrothermal process and Fe3+ mineral assemblage (Romero Silva, 1996).
Although analyses results are still controversial, the fact remains that there does not exist a scientific discussion to confirm categorically that the colour is due to the above-mentioned minerals, only simple inclusions within the quartz lattice structure.
On the other hand, from a geological point of view, the occurrence of magnesioriebeckite in dolerite rocks (metabasite) is rather rare worldwide as that mineral mainly forms in highly alkali-enriched rocks such as syenite, gneiss, granite, or even high-grade metamorphism schist (high-pressure metamorphism), which does not match with the current rock outcrops.
At the Antequera site, blue quartz crystals formed filling joints in highly weathered ophite blocks, where late residual silica fluids generated intense hydrothermal action.
Blue quartz crystals from this deposit reach up to 1 cm in size, with colours ranging from light bluish to deep blue (ultramarine). In conjunction with some similarly mineralized localities in the Cadiz province (Olvera, Torrealhaquime, and Coripe), the blue quartz crystal associations from Antequera ophites represent one of the most remarkable mineral assemblages worldwide, forming vugs and crystalline geodes of at least two generations of crystals which can overlap.
Moreover, the mineral formation on rare sub-volcanic dolerite rocks named "Ophites" and gemmy crystalline character, make the outcrop outstanding and well-distinguished.
The Juanona Quarry deposit is formed by a conical body of green subvolcanic ophite-dolerite intruded in Keuper Triassic gypsum-clayey-carbonates series (olistostrome). Ophites are often highly weathered and hydrothermalised along joints with ankerite, hematite, secondary gypsum, blue quartz, and aerinite formation. Blue quartz crystals are filling joints (0.5-1 cm) within highly fractured and weathered ophite rock (basic subvolcanic dolerite rock with intergrowth of plagioclase-augite texture). The blue quartz crystals are frequently coated by pale-cream carbonates, gypsum, and grey submetallic hematite. In some other areas, the quartz crystals are formed on highly weathered unconnected olistoliths of ophites which settled in gypsum-claystone sequence. Blue quartz crystals have also been reported on massive white gypsum (alabaster).

Formula: (Ca5.1Na0.5)(Fe3+,Al,Fe2+,Mg)4(Al,Mg)6[HSi12O36(OH)12][(CO3)1.2(H2O)12] Description: Alleged by some to be present at La Juanona, and to be the cause of the color in the famous local blue quartz crystals, apparently based just on the colour, habit, and ophitic association. Analyzed specimens of the fibrous material associated with blue quartz are riebeckite - magnesioriebeckite, but some other specimens allegedly turned out to be aerinite-riebeckite intergrowths. No analyses have been published, and the ID remains questionable. References: |

He empleado SEM (microscopía electrónica de barrido; Philips XL-30LV, 15 kV, BS, presión controlada 0,3 torr, sin recubrimiento), EDS (análisis de emisión de rayos X por dispersión de energía; EDAX UTW Sapphire) y XRD (difracción de rayos X, Philips Xpert, 45 kv, 40 mA). Así, tanto la morfología (vista por SEM, apreciándose el material formado por fibras), como la composición (determinada por EDS, con exiguo contenido en carbono y relación elemental que se ajusta a la estequiometría propia de la serie riebeckita-magnesioriebeckita, con algo de calcio substituyendo al Mg) y la estructura cristalina (establecida por XRD, donde la fase detectada con claridad, además del cuarzo, es riebeckita) confirman que no es aerinita, sino una riebeckita con parte del Fe substituido por Mg y Ca, aunque sin llegar a la estequiometría extrema de la magnesioriebeckita." - Juan Miguel Jiménez |
