ⓘ Acanthite
Formula: Ag2S
Description: Acanthite occurs as fibrous radiating tufts of black crystals less than 100 µm in size, deposited on dendrites of native silver. The X-ray powder pattern is similar to that of synthetic acanthite (JCPDS 14-72). Qualitative chemical analysis confirms the presence of major Ag and S, together with minor Cu, Zn, and Cl.
ⓘ Actinolite

Localities: Reported from at least 6 localities in this region.
Habit: Asbestiform fibres up to 4cm
Colour: brown
Description: "The actinolite from Challes has been analysed by electronic microprobe by Schreyer and Abraham (1978) who underline the variability of its chemical composition." (Hatert et al., 2002)
ⓘ Akaganeite
Formula: (Fe3+,Ni2+)8(OH,O)16Cl1.25 · nH2O
Colour: brown to brown-red
Description: Thin layers resembling delvauxite in small geodes in fractures of radioactive material observed in a pocket of Paleozoic limestone. Its conchoidal fracture often reveals a zoned texture. (Mélon et al., 1976 and Hatert et al., 2002)

ⓘ Strunzite
Formula: Mn2+Fe3+2(PO4)2(OH)2 · 6H2O
Habit: radiating rosettes
Colour: straw yellow to greyish yellow
Description: Van Tassel (1966) originally described "his" material as being "a strunzite-like material, completely Mn-free and with little or no divalent FeO". However, due to a lack of sufficient data, it was not submitted as a possible new species at the time. Later, Peacor et al. (1987) state that the mineral they name "ferristrunzite" is "essentially the Fe3+ analogue of strunzite and ferrostrunzite", i.e. exactly the same "Mn-free strunzite" as reported by Van Tassel back in 1966. In 1990, when Dillen & Van Goethem described ferristrunzite from Haut-le-Wastia (Dillen, H., Van Goethem, L. (1990) Ferristrunzite. Bulletin van de Belgische Vereniging voor Geologie, 99(3-4), 399), Van Tassel confirmed again that any and all "strunzite" from Blaton he had analysed over the years, had turned out to be recently named ferristrunzite (Rik Dillen, pers. comm.)

ⓘ Wurtzite
Formula: (Zn,Fe)S
ⓘ Wurtzite var. Voltzite ?
Formula: (Zn,Fe,Mn) S [with O C H ]
Habit: botryoidal globules on quartz crystals
Colour: Yellowish brown
Description: Mélon et al. (1976): "In the collections of the University of Liège, a specimen originating from the Bleiberg and described by Buttgenbach (1921) carries the name of "voltzine". The mineral is in the form of small botryoidal globules covering quartz crystals. Light yellowish brown, these globules, with a density of 3.79, scratching fluorite, show a concentric texture with accumulation of small golden yellow scales in very weakly birefringent thin scales. They fall apart in the closed tube and are soluble with effervescence in hydrochloric acid. The X-ray study, recently done by Fransolet, reveals a diffuse powder diagram; the size of the rays does not permit precise measurements, but the distances found are close enough to those of the powder diagram of sphalerite. Voltzite: 3.08 2.64 1.91 1.61 1.34 1.23 Å Sphalerite: 3.12 2.70 1.91 1.63 1.35 1.24 Å The look of the diagram and the similarity with sphalerite recall the observations of Fournet (1833) and Frondel (1967) on voltzites from Sterling Hill (New Jersey) and from Roisiers (Puy-de-Dôme). These two authors have shown, on the other hand, that voltzite is just a mixture of sphalerite with an organometallic compound of zinc, resulting from the precipitation of a gel."
