RM2690   Sulphur and calcite

Cáucaso mine, Conil de la Frontera, Cádiz, Andalucía, Spain

In this specimen we can see various sulfur aggregates, one of them in the form of a dipyramidal crystal. They are disposed in cavities lined with calcite. The banding of the matrix is perfectly observed. A classic locality for fine crystallized sulfur specimens since 18th century. Probably the area has been worked since Roman times. Very difficult to see in the market. Interesting video of sulphur mines from Conil [video].

Astor collection (Barcelona), can be dated to this period. The specimen shows several pyromorphite crystals, of good size, brilliant, translucent, thick and with shapes of the hexagonal barrel shaped prism, with the characteristic color between green to yellowish-green.

RM2263   Covellite and sulphur

Corta Atalaya, Minas de Riotinto, Huelva, Andalucía, Spain

his good sized specimen from the late 80s belongs from the Arguijo collection, and it was mined in this famous "onubense" mine. It is a sulphide matrix partially covered by brilliant covellite microcrystals, very defined and visible. It has an intense metallic blue iridescence and this very characteristic color. It is accompanied by numerous crystals of native sulphur with curved faces, brilliance, translucent and showing a delicate yellow tone. It was mined from a sporadic finding in the Corta Atalaya, Minas de Riotinto. A unique occasion to obtain one of these "old" specimens.

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.

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.

RM2043   Luzonite and Chalcocite

Las Cruces mine, Gerena, Sevilla, Andalucía, Spain

In this specimen, we observed some sulfide aggregates very characteristic of Las Cruces mine. They were partially covered with calcite and under it appear groups of very brilliant chalcocite crystals. But the most interesting part of this specimen are the small, very brilliant crystals those cover sulphides. It is an unusual species: Luzonite. Luzonite is a rare copper sulfoarsenide. I have made the relevant analysis that yields consistent results: S 35.19%, Cu 41.82%, As 22.99% (%wt). You can find more information at espiadellabo.com.

RM2042   Baryte Pb rich

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: 10.2 x 6.5 x 3 cm.
Main crystal: 7 mm.
