RM2918   Willemite

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

The Sant Fost willemite appears in small crystals with a pseudohexagonal prismatic habit (twinned), with striated faces. All of them are sub-millimetric in size and form druses of crystals with a resinous or adamantine luster, with colors ranging from dark brown to honey-yellow, or they may appear colorless and transparent. In Sant Fost the willemite appears associated to a sphalerite vein together with silicates (quartz and clays), calcite, fluorite, and baryte. Willemite is fluorescent under SW-UV light. Very unusual locality for the species.


Size: 3.8 x 1.7 x 0.9 cm.
Found in 2021.

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.


Size: 3.9 x 3.7 x 2.5 cm.

RM2916   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.

RM2655   Quartz (amethyst var.) and fluorite

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

Very "brilliant" specimen in the shape of a druse, with a pegmatitic matrix, accompanied by yellow fluorite crystals and upholstered with really brilliant quartz crystals, with an amethyst tone. These specimens were a rarity then and today.

The Sant Marçal mines (also known as Matagalls) are located in the Montseny massif, on the eastern slope of the Matagalls peak (1,700m). The works are between about 1,250 to 1,350 m of altitude. The municipal term corresponds to Viladrau. Mining in this type of deposits in this area and surrounding areas has focused on the extraction of minerals of Pb, Zn, F and Ba. Together with the Osor and Tagamanent deposits, the Rigròs vein of Sant Marçal mines is one of the most important in terms of the extraction of fluorite. Mines were operated until the mid-1990s and have been partially restored. Currently this area belongs to the Montseny Natural Park, so the collection of specimens is totally prohibited.

These mines were operated until the mid-1990s and have been partially restored. Currently this area belongs to the Montseny Natural Park, so the collection of specimens is totally prohibited.
