Rosell Minerales

The schorl specimens from Cap de Creus are well known to Spanish mineral collectors. This specimen from the 70s of the last century shows us a striated prism and defined facets of the terminal faces, something unusual. This area of the NE of Catalonia is now a Natural Park and it is totally forbidden to extract specimens.

Size: 5.9 x 4.4 x 3.4 cm.
Main crystal: 1.5 x 1 cm.
Found in ±1970.

Col. Joan Astor (Barcelona).
Classic locality

Andalusite specimen from Cap de Creus (Cape), with pink tones and quite crystalline. The Cap de Creus Natural Park was the first maritime-terrestrial park in Catalonia. It was created in 1998 and protects a large part of the Cap de Creus peninsula. Currently totally prohibited to collect minerals in this area.

Size: 6 x 3.4 x 2.8 cm.
Found in ± 1976.

Col. Joan Astor (Barcelona).
Classic locality

Good schorl specimen from the clssic locality of Cap de Creus, Girona. Some crystals showing a developed and faceted prism and terminal faces, some of them with good thickness. From this locality it is very difficult to obtain specimens if they do not appear in old collections, as it is the case, since it is totally forbidden to collect specimens in the area. This one belongs from the Manchion Collection and it is accompanied by the handwritten label.

Size: 7.3 x 7 x 4.6 cm.
Main crystal: 2.1 cm.
Found in ±1980.

Classic locality

An old piece from el Cap de Creus (Creus Cape), in Girona. It presents different almandine crystals, with colour between pink to orange, some altered, others faceted, which are included in a matrix of pegmatite. They are accompanied by black schorl. Nowadays it is forbidden to collect anything in that area and it is difficult to find available pieces.

Size: 6.5 x 4.5 x 3.8 cm.
Main crystal: 6 mm.
Found in ±1978.

These samples of heterosite come from a classic area for the Catalan mineralogy such as Cap de Creus, in Girona. They belong from a former collection and were collected, according to the owners, by the 70s of the last century. Currently, in the Cap de Creus area, it is strictly forbidden to collect absolutely anything. These samples show aggregates of brownish-black tones, with a certain brightness, with layers of violet color and embeded in a pegmatitic matrix. No acid applied.
Bareche, in his work "Els Minerals de Catalunya, Segle XX" (2005), indicated the presence in this area of several rare Mn and Fe phosphates. He indicated that the purpurite was found in a single outcrop as small masses of violet and brownish color, along with heterosite from brown to black. From these specimens, several fragments of violet tone have been analyzed. The results have indicated that iron is predominant, with a ratio Fe:Mn, 2:1, consistent with heterosite. We do not rule out that purpurite (Mn> Fe) could be present, as member of heterosite-purpurite series.
