RM450   Pyromorphite with barite
Pb₅(PO₄)₃Cl
  -  8. Phosphates, arsenates and vanadates

On a barite matrix are disposed several sharp pyromorphite crystals with a very interesting color olive-green color. They have grow in divergent directions. Some of the crystals are isolated, with an elongated prism. Really excelent specimen. A classic between classics from this well known french mine closed in 1981. A great opportunity for pyromorphite and old classic mineral collectors.

Size: 6,8 x 4,5 x 3,4 cm.
Main crystal: 10 x 2 mm.

RM448   Pyromorphite with quartz and barite
Pb₅(PO₄)₃Cl
  -  8. Phosphates, arsenates and vanadates

On a quartz matrix are disposed some sharp pyromorphite crystals with a very interesting color zoning between light green in prism faces and yellow tones on terminal pinacoids. Crystals show a hexagonal barrel-shaped prism with flattened terminal faces on the top. They have grow in divergent directions. Some of the crystals are isolated, with an elongated prism. A classic between classics from this well known french mine closed in 1981. A nice specimen of pyromorphite.

Pb₅(PO₄)₃Cl
  -  8. Phosphates, arsenates and vanadates

On a barite matrix are disposed several sharp pyromorphite crystals with a very interesting color zoning between olive-green in prism faces and yellow tones on terminal ones. Crystals show a hexagonal barrel-shaped prism with the pyramid terminal faces on the top. They have grow in divergent directions. Some of the crystals are isolated, with an elongated prism. Contrasting with the dark brown matrix. A classic between classics from this well known french mine closed in 1981. A great opportunity for pyromorphite and old classic mineral collectors.

RM384   Bastnäsite-(Ce) with talc and dolomite

This specimen is from a worldwide classic mine for Rare Earth Elements (REE) species. We observe two groups of defined tabular hexagonal crystals with small pyramidal faces. They show a good transparency and color that varies between yellow-green to orange-brown, depending on the type of the light that strikes them. Currently it is not easy to find bastnäsite-(Ce) specimens from this mine and with this crystal size.

Size: 6,8 x 4,4 x 3,8 cm.
Main crystal: 6 x 4 mm.
Found in 2007.
It shows Pleochroism

RM328   Metatorbernite with smoky quartz
Cu(UO₂)₂(PO₄)₂·8H₂O
  -  8. Phosphates, arsenates and vanadates

A very rich group of sharp metatorbernite crystals showing tabular tetragonal forms, an intense green color and good luster. They show polysynthetic and echeloned growths, and also as isolated tabular crystals. We can observe a yellowish fluorescence due to the presence of metautunite. This species is visible also as yellowish tones in the core of some exfoliated crystals. A French mineralogy classic not seen since late 70's.

These specimens come from a mineralized vug found in 2009 from were were obtained several floating specimens and some with stalactitic shape. The walls of the fissure were covered by smoky quartz crystals. When samples are mined and pull out of the mine, a partially dehydratation occurs (from 12 to 8 H2O molecules) and torbernite become metatorbernite species. Margabal specimens can be classified as metatorbernite.
