Classic locality

Tabular metazeunerite crystals, of a pale green color, forming aggregates in a cavity of the matrix. On one of these aggregates, an aggregate of pale yellow methanováčekite crystals is disposed. It belongs from this classic Moroccan mine. The uranium-rich zone (vein 2) of the quarry had been covered.

Size: 3.9 x 3.2 x 1.9 cm.
Found in ca. 2006.

Presents radioactive activity.

A really interesting good size and gemmy fluorapatite crystal. We can observe perfectly the combination of the first and second order prisms; very sharp terminal faces, with first order hexagonal dipyramid. A specimen to enjoy crystallography and aesthetics.
Crystal shows excellent brilliance, transparence and a vivid yellow color with green tones. The specimen is from a Moroccan classic mine located in the Imilchil mountains area.

Size: 2.6 x 1.3 x 1.2 cm.
Found in ca. 2012.

Classic locality

Druse of quartz crystals, milky to hyaline at the tips, with a certain reddish hue. It comes from a Moroccan locality unknown in collections, located in the Boulemane area, north of Aouli. Formed in volcanic rocks.

Size: 8.2 x 7 x 5 cm.
Main crystal: 0.8 x 0.7 cm.

Hemispherical aggregate of smithsonite crystals, of good size, luster and with a very curious orange-brown color. On the label of the A. Trigo (Mataró) collection it indicates that he bought this specimen from a Moroccan dealer (1989) as "tornuisite", a term for which we have not found references, unless it was wrongly confused with "tarnowizite". Touissit specimens of globular smithsonite are known but rare.

Size: 5.6 x 4.5 x 3 cm.
Found in ca. 1989.

Col. Antonio Trigo (Mataró).

Group of cubic fluorite crystals, with good brilliance, transparence and a very characteristic green color. From this classic Moroccan mines. With the label of the former collection Trigo (Mataró).

Size: 4.7 x 3.5 x 2.7 cm.
Main crystal: 2.2 cm.

These specimens of manganite partially replaced pyrolusite, come from a locality not yet described in the mineralogical bibliography. This deposit is located in the province of Boulemane, in the Fez-Meknés region, about ten kilometers from the well-known Aouli mines. It is a formation very similar to that of Imini (near Ouarzazate). These manganese deposits, both in Imini and in the Boulemane area, were formed in a karst system. Associated with shallow marine dolomites of the Cretaceous age and that currently form sub-horizontal mantles cutted by erosion, overlaping areas of volcanic rocks. Manganese minerals are found in dolomite breccia and ferruginous clays. We have carried out X-ray diffraction studies showing us the presence of both species: manganite and pyrolusite.

Analyzed specimen with report

On a recent trip to this mining area, we found these new specimens with incredible aesthetics. They were found in a singular cavity, opened in the depths of a 24-meter well, in Coud'a shafts. They have a more than exceptional brilliance, probably due to a last phase of crystallization in which a thin layer of almost transparent vanadinite was deposited. Crystals are very well defined, with staggered axial growths in the prism and with color zoning, more orange than red. Contrasting on a solid rocky matrix. Vanadinites from the Mibladen area are well known worldwide and although we have seen many of them, they never cease to amaze us. Amazing specimens!

On a recent trip to this Moroccan mining area, we found these stalactitic specimens of vanadinite with incredible aesthetics. They were found in a singular cavity, opened in the depths of a 24-meter well, in the Coud'a shafts area. They have a really good brilliance. Crystals show attractive stalactitic growths, also uneven developments in the directions of the prism, very well defined, interpenetrated and with some color zoning. Vanadinite specimens from Mibladen area are well known iworlwide and although we have seen many, they never cease to amaze us. Exceptional specimens.

Classic locality

Galena crystals from the Mibladen mines are not easy to see today, least of all with this definition. They are cubic crystals, with well-marked faces and edges. Some interpenetrated, some very aerial. They are arranged on a matrix with baryte rosettes.

Size: 10 x 4.5 x 4 cm.
Main crystal: 6 mm.
Found in ca. 1980.

Col. Arguijo (L'Hospitalet de Llobregat, Barcelona)
Classic locality

Specimen of azurite with a very special, intense color, formed by numerous small crystals, very brilliant. On baryte matrix. They belong to the mine that exploits the immense Marabout vein, located in the north of Sidi Ayed. The coordinates of the mine are 32°53'23''N, 4°38'33''W. Near from Mibladen but in the other side of the mountains.

Size: 6.5 x 3.5 x 3 cm.
