Located only 200/250 meters from Salmchâteau.

Comprises the Le Coreux mine (250 meters from Salmchâteau) and an outcrop of quartz veins (200 meters from Salmchâteau), both to the west of the small road from Salmchâteau to Vielsalm (the Rue du Vivier or Basse Ville).

Late quartz veins in viridine/kanonaite-bearing phyllites of Ordovician age.

Detailed Mineral List:

ⓘ Albite
Formula: Na(AlSi3O8)
ⓘ Andalusite
Formula: Al2(SiO4)O
Description: Small rounded crystals (0.5 mm) in dark violet banded shale.
ⓘ Andalusite var. Viridine
Formula: (Al,Mn3+)2SiO4O
Description: Small rounded crystals (0.5 mm) in dark violet banded shale.
ⓘ Ardennite-(As)
Formula: Mn2+4Al4(AlMg)(AsO4)(SiO4)2(Si3O10)(OH)6
ⓘ Arsenogoyazite
Formula: SrAl3(AsO4)(AsO3OH)(OH)6
ⓘ Braunite
Formula: Mn2+Mn3+6(SiO4)O8
Habit: fine blades parallel to the stratification; fine-grained
Colour: creamy grey with a brown tint (thin section)
Description: Intimately associated with kanonaite. Microprobe analysis reveals the presence of Ba and Sr in low proportions (Schreyer et al., 2001).
ⓘ Clinochlore
Formula: Mg5Al(AlSi3O10)(OH)8
Description: Fe-poor excess-Al clinochlore.

Habit: very thin needles up to 2mm
Description: Hollandite Sr-end member up to 60% associated with braunite.
ⓘ Kanonaite
Formula: Mn3+Al(SiO4)O
Description: Mn is located in the Jahn-Teller dislocated octahedron of the andalusite-type structure. Mn3+ concentration increases with decreasing temperature (anti-clockwise P-T-t path of extensional metamorphism).
ⓘ Kaolinite
Formula: Al2(Si2O5)(OH)4
Description: Retrograde breakdown reaction of less Mn-rich kanonaite.

ⓘ Muscovite
Formula: KAl2(AlSi3O10)(OH)2
Description: Replaces kanonaite (rims). Ca/Mg/Ba-bearing muscovite (W. Schreyer et al. , Contributions to Mineralogy and Petrology, Vol. 141, Issue 5, 2001, pp. 560-571. ).
ⓘ Piemontite
Formula: (CaCa)(AlAlMn3+)O[Si2O7][SiO4](OH)

Type Locality:
ⓘ Strontiomelane
Formula: Sr(Mn4+6Mn3+2)O16
Habit: thin acicular crystals up to 2mm
Description: Associated with braunite and/or kanonaite. Microprobe analysis shows the replacement of Ba by Sr of up to 60%, resulting in the mineral strontiomelane.
