RM1664   Wendwilsonite with aragonite, talmessite

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

Aesthetic specimen of wendwilsonite formed by numerous sized and isolated crystals, transparent, very well defined, some of them doubly terminated. With an intense and uniform pink color. In the back side, we have a druse very rich in crystals. They are disposed on a matrix with brilliant calcite crystals and dolomite. Some talmessite crystals with an orange tone are asociated. The sample has been analyzed and we will send all results to the buyer. The sample has been analyzed by SEM-EDS and Raman. The results indicate a very low Co content and the Raman indicates that it is wendwilsonite. We will send the buyer all the details.

RM1672   Nakauriite with tremolite and talc

Rodionovskoe chromite mine, Ufaley, Chelyabinsk Oblast', Urals, Russia

Nakauriite is a rare hydrated magnesium and copper carbonate, but old formula was Cu8(SO4)4(CO3)(OH)6·48H2O. The sulphate content, originally reported, seems to be questionable according to literature; the crystalline structure is unknown. Palenzona and Martinelli (2007) suggest a formula (Mg,Cu)x(CO3)y(OH)z·nH2O (x, y, z unknown). It appears as fibrous and nodular aggregates of bluish color embedded in the matrix of tremolite/talc. This specimen has an unusual size and is very rich. It comes from the abandoned chromite mines in Ufalei chromite deposits.

RM1670   Rhodochrosite

Potosí mine, Aquiles Serdán, Santa Eulalia, Chihuahua, Mexico

Very rich specimen of rhodo, formed by several gemmy, rose-red elongated rhombohedrons covering the matrix on this fine, fine quality sample from the famous 1970s and 1980s finds at Santa Eulalia. Observed under magnification we can see that elongated faces are semidull and terminal rhombohedrons are brilliant and transparent. Color is really good. Not easy to find in the market specimens with this quality.

RM1665   Nepheline and schorlomite

Jebel Bou-Agrao, Tamazeght Mts., Khénifra, Béni Mellal-Khénifra, Morocco

A vug that is lined with sharp, hexagonal, grayish-white nepheline crystals, accompanied by lustrous, black crystals of schorlomite as dodecahedral crystals. Schorlomite is a rare garnet group member and much of the material labeled "schorlomite" is, strictly speaking, titanian andradite. Excellent, highly representative combination material of the species. Not very often one can see well formed nepheline crystals of this species, especially crystals this size. Very aesthetic specimen from Jebel Bou-Agrao.

Main crystal: 20 x 12 mm.

 

RM1666   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 gold and electrum in Bou Azer was already described, but the quality of these specimens we offer surpasses what was known. A very rich gold-electrum specimen.
