RM1874   Talmessite with cobaltoan calcite

Aghbar Mine, Aghbar, Bou Azzer, Tazenakht, Ouarzazate, Morocco

Interesting specimen formed by several aggregates of tabular talmessite crystals, standing out on the calcite matrix. In order to confirm the species, we carried out a chemical analysis using SEM-EDS, which confirms the presence of Ca and Mg and the almost absence of Co, consistent with talmessite or wendwilsonite. On the other hand, X-ray diffraction confirms talmessite. Performing this structural (XRD) and compositional analysis (SEM-EDS) allows us to delimit the species. Spheroidal aggregates of slightly curved faces and edges. Color and luster are magnificent for the species and contrast on a base of small slightly pink crystals of calcite (Mn), on matrix. We'll send a the analysis to the buyer.


Size: 6.8 x 4.8 x 4.7 cm.
Main crystal: 3 mm. aggr.

RM1857   Talmessite with cobaltoan calcite

Agoudal, Bou Azzer, Ouarzazate, Drâa-Tafilalet, Morocco

Very curious globular aggregates formed by prismatic crystals that vary their composition according to the zone, although the XR diffraction study shows that it is talmessite, without discarding that in some parts of the aggregate a higher cobalt content is observed. These aggregates are disposed on a matrix of cobaltoan calcite, together with manganese oxides. Very interesting.

RM1765   Silver cubic crystals

Aït Ahmane (filon 53), Bou Azzer, Ouarzazate, Drâa-Tafilalet, Morocco

This specimen stands out for showing arborescent growths of very well defined silver cubic crystals. In addition, the piece comes from a Moroccan mine from which few samples of this type and quality have been collected. To add more importance to the piece, it must be said that the calcite has been partially removed by mechanical procedures, without acids that could cause the silver to blacken. Well defined, extremely brilliant and isolated silver crystals are not very common, usually appear deformed or in complex growths. An excellent and good sized specimen (several photos attached).


Size: 10.5 x 5.5 x 3.6 cm.



 

RM1755   Gold, var. electrum and Erythrite

Taghouni mine, Taghouni, Bou Azer, Tazenakht, Ouarzazate, Morocco

These specimens show a matrix formed by arsenates such as erythrite and associated sulphides and arsenates of cobalt and iron. We can observe on both the presence of arborescent, filiform and laminar gold aggregates. SEM analysis has shown that this is a variety of gold rich in silver (23-24%w): electrum.
Under loupe, we can enjoy that some of these gold aggregates are formed by small crystals of octahedral to cubic forms. We can theorize a secondary genesis for this gold-electrum. We have analyzed the matrix of these specimens observing that the bright metallic matrix corresponds to a mixture of cobalt arsenides, probably skutterudite, and other sulphides. We will send all analyzes to the buyer. The deposit where the electrum appeared has been totally covered by mine lands, so more samples can not be obtained on the field. A very rich gold-electrum specimen.
