RM2777   Willemite, siderite, galena and goethite

Rivet Quarry, Montredon-Labessonnié, Réalmont, Tarn, Midi-Pyrénées, France

Numerous groups of prismatic willemite crystals in the cavities of this matrix with galena, siderite, quartz and goethite. The crystals show hexagonal shapes truncated by pinacoidal faces, they appear isolated or forming aesthetic stars. Some of them are dotted with rhombohedral crystals, between honey-colored to greenish, of siderite. Fluorescent under short wave UV light. A good size specimen of this classic Occitan Pb-Zn mine.


Size: 8.7 x 5.1 x 3.8 cm.
Main crystal: 1.5 mm.

Fluorescent under short wave UV


 

RM1581   Pyromorphite

Saint-Salvy mine, Saint-Salvy-de-la-Balme, Tarn, France

A very rich specimen formed by several aggregates of acicular to prismatic pyromorphite crystals with an intense green color and silky luster. On a rocky matrix. A French classic from old "times".


Size: 5.3 x 4.0 x 3.5 cm.

 

RM851   Goethite with siderite

Mont-Roc Mine, Villefranche d'Albigeois, Tarn, Midi-Pyrénées, France

Botryoidal aggregates formed by goethite microcrystals, with a delicate velvety appearance with deep brown to black color zoning. In section we can observe the radial arrangement of goethite crystals. The matrix is a mixture of goethite with some siderite rhombohedrons. These specimens are from a find in the Mont-Roc mine, that is known for the French mineralogy for its brilliant goethites and fluorite.


Size: 7.0 x 5.5 x 5.0 mcm.
Found in 2014.

 

RM849   Goethite with siderite

Mont-Roc Mine, Villefranche d'Albigeois, Tarn, Midi-Pyrénées, France

Botryoidal aggregates formed by goethite microcrystals, with a delicate velvety appearance with color zoning that varies between brown garnet to dark gray. In section we can observe the radial arrangement of goethite crystals. The matrix is a mixture of goethite with some siderite rhombohedrons and quartz. These specimens are from a recent find in the Mont-Roc mine, that is known for the French mineralogy for its brilliant goethites and fluorite.


Size: 11.5 x 7.5 x 5.0 cm.
Found in 2014.

 

RM816   Rhodochrosite with kentrolite

Rivet Quarry, Montredon-Labessonnié, Réalmont, Tarn, Midi-Pyrénées, France

This specimen shows stalactític aggregates of rhodochrosite with a pink color. They are accompanied by brilliant botryoidal kentrolite, with a deep black color. It is a rare lead and manganese silicate. Nice specimen for the species and dedicated to systematic and French collectors.
