RM3008   Fehrite and devilline

Les Ferreres mine, Rocabruna, Camprodon, Girona, Catalunya, Spain

Fehrite is a recent new species found in Almeria (Spain). Some years ago (2012) we identified this species in the Les Ferreres mine (Camprodon) but unfortunatelly we didn't have enough sample to finish detrmination and structural studies. Recently we found some more samples and the characterization was carried out based on the results obtained from the application of various analytical techniques: SEM-EDS, Raman and X-ray diffraction. Les Ferreres mine is the second locality worldwide for the species. We will send all reports to the buyer.
In this Catalan mine, fehrite appears as elongated elongated tabular to fibrous crystals, with a delicate bluish-green tone, and fibrous terminations. Usually, it is accompanied by devilline (blue) and brochantite (green). It is the magnesium analogue of ktenasite.

RM2983   Baryte and limonite

Els Frares Quarry, Aiguafreda, Vallès Oriental, Catalunya, Spain

Baryte crystals from this quarry are a classic of Catalan mineralogy. They appear in the fissures of the slates, usually covered by iron oxydes. In this specimen we can see various groups of prismatic crystals, brilliant and transparent, rich in faces. Among them, a larger one stands out in which we can see the faces of orthorhombic prisms of various orders truncated by pinacoidal faces. Nowadays it is very difficult to find specimens in this quarry and even less with the quality we offer.

RM2981   Fluorite and quartz

Sant Marçal (Matagalls) mines, Sant Marçal, Massís del Montseny, Viladrau, Girona, Catalunya, Spain

Fluorite specimens from Sant Marçal mines usually appear as aggregates of cubic crystals, defined, sometimes sprinkled or partially covered by quartz crystals. Yellow to greenish tones are the usual ones. Specimens with violet to bluish colors (depending on the type of incident light) are much less frequent and highly appreciated by collectors. These specimens we offer were collected at the beginning of the 70s. Some small nick, very common in these specimens, without affecting the quality. In this specimen we can observe cubic crystals with this bluish to greenish tone, translucent and disposed on a characteristic ochy "pegmatite" matrix. They are partially covered and on with small but brilliant quartz crystals.

RM2969   Fluorite and quartz

Sant Marçal (Matagalls) mines, Sant Marçal, Massís del Montseny, Viladrau, Girona, Catalunya, Spain

Fluorite specimens from Sant Marçal mines usually appear as aggregates of cubic crystals, defined, sometimes sprinkled or partially covered by quartz crystals. Yellow to greenish tones are the usual ones. Specimens with violet to bluish or green colors (depending on the type of incident light) are much less frequent and highly appreciated by collectors. These specimens we offer were collected at the beginning of the 70s. In this specimen we can observe cubic crystals with this bluish to greyish tone, translucent and disposed on a characteristic ochy "pegmatite" matrix. They are partially covered with small but brilliant quartz crystals.

The Sant Marçal mines (also known as Matagalls mines) are located in the Montseny massif, on the eastern slope of the Matagalls peak (1,700 m). Mining works were carried out at 1,250 to 1,350 m of altitude. The municipality corresponds to Viladrau. Mining in this type of deposits in this area and surrounding areas had been focused on the extraction of minerals of Pb, Zn, F and Ba. Together with the Osor and Tagamanent deposits, the Rigròs main vein from Sant Marçal mines is one of the most important in terms of fluorite extraction. Although there are other less thin mineralized veins in the area. These veins are embedded in granodiorite rock, which locally present metric dikes with a pegmatite texture. the granodiorites are usually altered to "sauló" (coarse-grained sand with micas, clays and quartz grains) and in some specimens it forms part of the matrix. The paragenesis of these veins: fluorite, baryte, galena, pyrite, chalcopyrite and quartz (often amethyst variety). They were mined until the mid-90s and have been partially restored. Currently this area belongs to the Montseny Natural Park, so the collection of specimens is totally prohibited.

RM2917   Surite with cerussite and fluorite

Can Rovira quarry, Sant Fost de Campsentelles, Barcelona, Catalunya, Spain

This is one of the few samples obtained in our last studies in this quarry. We saw a mica-like platy crystals, with a pearly luster and hexagonal form. The results of the different analytical techniques indicated that it was surite (SEM-EDS, EPMA, XRD, Raman). It is accompanied by cerussite, fluorite (purple), baryte and galena.
Surite is a very rare species based on a cerussite-like layer intercalated with a 2:1 layer of smectite. Can Rovira is the second locality in Europe and one of the few localities worldwide.
