RM1924   Hematite
Fe₂O₃
  -  4. Oxides and hydroxides

Brilliant botryoidal hematite specimen. In the back side we observe very esthetic concentric growths of different colours, fibrous, of hematite. These pieces have been cleaned in origin with sand which eliminates the surface oxide layer to let us see these spherical forms of good size. Very curious Moroccan novelty.

RM1914   Gold with malachite and bornite

These are brilliant aggregates of gold formed by numerous crystals rich in faces, curved faces and disposed on a matrix of quartz. The SEM-EDS analyzes show that this gold contains a small percentage of silver (<1% weight). They are accompanied by fibrous aggregates of malachite and gray bornite crystals. This specimen stands out for the contrast between the brilliant gold and the green/gray matrix. An exceptional piece. Bleida is a mine located on the eastern rim of the Bou Azzer district.

RM1896   Pyurolusite replacing manganite

From what has been analyzed, Imini pyrolusites are partially replaced by manganite.

RM1874   Talmessite with cobaltoan calcite

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.
