RM1483   Andradite

Cala mines, Cala, Huelva, Andalucía, Spain

Druse of trapezohedral crystals of andradite from this classic Spanish locality. Intense brilliance, with colors between brown to reddish. On a granatite with epidote. This is a specimen with pedigree from the Gustav Beck collection.


Size: 6.7 x 4.2 x 3.6 cm.
Main crystal: 8 x 8 mm.

RM2060   Ferro-Pargasite with Calcite and Epidote

Cala mines, Cala, Huelva, Andalucía, Spain

Radial aggregates of ferro-pargasite with an intense luster and very deep green colour. Accompanied in the granatite matrix with epidote crystals and orange calcite. The ferro-pargasite of this deposit is the dominant amphibole in the granatite fissures, although it was classified as hastingsite according to data provided by the exploiting company (according to Miguel Calvo in Minerales de España, vol. IX); for this reason surely the label that accompanies this sample classifies it as hastingsite.


Size: 10 x 8.5 x 2.5 cm.
Main crystal: 35 mm fibr.
Found in ±1988

RM2061   Tremolite with actinolite and calcite

Cala mines, Cala, Huelva, Andalucía, Spain

Fibrous aggregate of tremolite crystals, very brilliant and with an olive green colour. They are accompanied by prismatic crystals of darker green actinolite and orange calcite. Good size and representative for the locality and the species. The Manuel-Mercedes open pit is embedded in the granitic intrusions that were accompanied by contact metamorphism and gave rise to the formation of the skarn, with important deposits of magnetite.


Size: 8.5 x 7 x 5.2 cm.

RM434   Pyrolusite

Salvadora mine, Cerro el Morante, Calañas, Huelva, Andalucía, Spain

Group of very sharp pyrolusite tabular crystals showing polysynthetic growths, unusual for the species. Good luster, metallic gray color. The echeloned faces gives them a different aesthetics. In the matrix we can observe more classic acicular radiated pyrolusite crystals.
Few specimens were obtained and, at first, it was thought that by their shapes and color tones they were marcasite, but further analysis characterized them as pyrolusite. Probably the best pyrolusite Spanish specimens.


Size: 4,6 x 2,7 x 1,6 cm.
Main crystal: 11 x 10 mm (group)
Found in 03/2011

 

RM399   Baryte

Cerro Salomón, Minas de Riotinto, Huelva, Andalucía, Spain

Druse of very sharp baryte crystals showing developed and striated prismatic faces, truncated by pinacoids. The crystals are translucent, and color varies between colorless to yellowish. Excellent brilliance. Similar specimens were classified, many years ago, as hokutolite (a lead-rich baryte variety) but further analysis showed that there was only a minor lead content.


Size: 7,0 x 4,5 x 3,2 cm.
Main crystal: 10 x 7 mm.

RM2041   Lead rich baryte

Cerro Salomón, Minas de Riotinto, Huelva, Andalucía, Spain

Druse of very sharp baryte crystals showing developed and striated prismatic faces, truncated by pinacoids. The crystals are translucent, and color varies between colorless to yellowish. Excellent brilliance. Similar specimens were classified, many years ago, as hokutolite (a lead-rich baryte variety) but further analysis showed that there was only a minor lead content.

RM1820   Iridescent goethite

Cerro Salomón, Minas de Riotinto, Huelva, Andalucía, Spain

Interesting example of goethite with a richness and very remarkable intense iridescences. From the classic mines of Riotinto; collected in 1985, accompanied by old label.


Size: 9.5 x 7.4 x 3.2 cm.
Found in 1985.

RM398   Copper

Herrerías mine, Corta Santa Bárbara, Puebla de Guzmán, Huelva, Andalucía, Spain

Arborescent growth of deformed and flattened native copper crystals. Some of them, smaller ones, still show complex cubic forms. Its color is the original and I preferred not alter it by chemical methods. In some of the branches we can see the brilliance of copper, but the rest has this "coppery" tone. It is disposed very aerial on the rocky matrix.
Nowadays the mine is flooded, so get new specimens is quite complicate, if not impossible. A classic mineral specimen from this “Spanish pyrite belt” locality.
