RM1874 Talmessite with cobaltoan calcite
Aghbar Mine, Aghbar, Bou Azzer, Tazenakht, Ouarzazate, MoroccoInteresting 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.

RM1755 Gold, var. electrum and Erythrite
Taghouni mine, Taghouni, Bou Azer, Tazenakht, Ouarzazate, MoroccoThese 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.
