RM2407   Metatorbernite with quartz

Calo, Vimianzo, A Coruña, Galicia, Spain

Group of very sharp metatorbernite crystals, one of them predominant, with an intense green grass color, showing the combination of the first and the second order dipyramids, truncated by pinacoidal faces. Its intense color gives a nice contrast with the white quartz matrix. Large open cast mines ans small prospects of kaolinite with some quartz veins in which torbernite crystals have been found. We could say that this locality is included in the most worldwide important torbernite localities due to the crystal quality, size and multiple habits.


Size: 6.7 x 3.9 x 2.3 cm.
Main crystal: 6 mm.

Presents radioactive activity.

RM2402   Pyromorphite

San Andrés mine, Espiel, Córdoba, Andalucía, Spain

Pyromorphite specimens from the San Andrés mine in Espiel, Córdoba, have been known since the first half of the 20th century. At the beginning of the 80s of this past century several quality specimens were recovered from the mine. This specimen, due to the date on the label of the J. 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. They fill a vug in the goethite matrix. A Spanish classic.

RM2245   Kyanite after andalucite

Touro - O Pino, A Coruña, Galícia, Spain

The specimens of this species have been known since ancient times as pseudomorphic kyanite after andalusite. Both species are polymorphic, so substitution is not a rare case. The label says "Santiago de Compostela", but from what we have investigated, it is the area of the Conceilhos de Touro and O Pino, to the E. of Santiago, where for decades this material was worked as kyanite. A piece with history ...

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.

RM2254   Actinolite

Can Serrat-La Mena mines, Sant Feliu de Buixalleu, Girona, Catalunya, Spain

These rare specimens of actinolite correspond to those cited by L. Thomas (Els Minerals de Catalunya, year 1920) and E.

It is shiny, greenish in color; we collected and kept specimens that were examined by Don Ramón Adan de Yarza, which confirmed our identification". It is a skarn formed by the contact of the granodiorites and the limestone of the Paleozoic. From the former Arguijo collection.

Hidalgoite specimen from this classic Spanish mine. It appears as olive-green coatings, forming aggregates of tiny crystals. Collected in 1999 by M. Marí and A. García. The Estrella mine is located in the Majadillas hill, in the extreme south of the municipality of Pardos, in Guadalajara. It is an old copper and silver mine whose exploitation dates back to the 17th century, with its maximum activity being in the mid-19th century coinciding with the splendor of the nearby Hiendelaencina mines.

RM2197   Pyromorphite with coronadite and quartz

Bedures Hill, Meredo, Vegadeo, Asturias, Spain

As M. Calvo indicates in his work (Minas y mInerales de España), in the area of Bedures hill (or Vidures), in the municipality of Vegadeo, there are several mining works, some of them very ancient, in which various lead mineral species have been described and among them, pyromorphite stands out. This piece we propose, found by chance in a mineral show far from the mine that saw it born, shows a matrix of milky quartz, with iron oxides and a black layer of coronadite in one side. We can observe also several crystals of green pyromorphite on the surface. Some form divergent aggregates, others isolated, but with an intense green color, with zoning in some of them. They show hexagonal prisms truncated by pinacoidal faces and parallel growth aggregates. A very rare specimen for this Spanish locality.
