3N1-NYKPyromorphite Pb5(PO4)3Cl , Galena PbS , Cerussite PbCO3
Dimensions: 75 mm x 75 mm x 50 mm
The contours of the galena cube were epigenized by pyromorphite.
The heart of the crystal still contains galena encrusted with a mineral that I have not been able to identify.
There are also traces of hydroxyapatites on the outline of the cube.

25N-3X5Pyromorphite Pb5(PO4)3Cl , Galena PbS , Cerussite PbCO3
Dimensions: 65 mm x 55 mm x 45 mm
Here the pyromorphite has crystallized in covering of the galena.
One can observe galena cubes covered with hilly pyromorphite.
Cerusitis is very present.

6JM-NQ0Baryte BaSO4 , Fluorite CaF2 , Quartz SiO2
Dimensions: 90 mm x 80 mm x 80 mm
Barite, rarely seen on the Argentolle site but very present.

TKN-1C2Fluorite CaF2
Dimensions: 65 mm x 60 mm x 45 mm
Largest Crystal Size: 20 mm
Multigeneration fluorite released with fluoridric acid.
Crystals are curved octahedra.
The last generation presents incomplete crystallizations

1Q7-T10Fluorite CaF2
Dimensions: 90 mm x 70 mm x 40 mm
Largest Crystal Size: 20 mm
Multigeneration fluorite released with fluoridric acid.
Crystals are curved octahedra. Because of their intergeneration, the colors are different at heart.
The last generation presents incomplete crystallizations either by lack or by dissolution.

AY7-CFLFluorite CaF2
Dimensions: 140 mm x 100 mm x 85 mm
Largest Crystal Size: 14 mm
Fluorite of several generations, the most recent crystals of which have a cubic termination.
The sample was prepared with fluoridric acid to show the yellow cubes.
This fluorite comes from the Mont Chevret vein.

JF6-TYGAragonite CaCO3
Dimensions: 110 mm x 70 mm x 65 mm
A rare sample of neo-formation Aragonite.
The deposit is very probably contemporary with the opening of the geode. The aragonite is still visible in the geode. To my knowledge, this is the only sample taken from this geode.

XQK-FUQFluorite CaF2 , Quartz SiO2
Dimensions: 80 mm x 80 mm x 65 mm
Largest Crystal Size: 30 mm
Fluorite with red and purple hematoid phantoms at heart.
Partially dusted with small red quartz as well.
The crystals are cubic with polysynthetic endings.
This sample was probably collected by a miner in the 1980s.

Largest Crystal Size: 6 mm
View of the truncations of a fluorite crystal.
Very pretty lemon yellow color.

Carrière noyée, Rocher du Boeuf
Open-air mine named "Rocher du Boeuf" completely submerged.
Little by little, nature is taking back what belongs to it.
