RM2560   Phacolite, chabasite var.

Gads Hill, Upper, Mersey Valley, Meander Valley, Tasmania, Australia

Colorless, vitreous and brilliant phacolite crystals covering the volcanic rock matrix. Phacolite is a variety of chabazite, with a pseudohexagonal lenticular shape, due to the twinning of several rhombohedrons. A very nice miniature from the former Trigo collection, from Mataró (Catalonia), with its handwritten label.


Size: 3.4 x 2.5 x 1.5 CM.
Found in ±1985.

Col. A. Trigo, Mataró.


 

RM2470   Natrolite

Cape Grim, Circular Head, Tasmania, Australia

Globular aggregates of prismatic natrolite crystals, with well defined terminal faces. It comes from a locality well known for its zeolites. Nowadays this Cape Grim area is restricted access due to wind turbines field. From the former A. Trigo Collection (Mataró).


Size: 6 x 5.5 x 2.6 cm.
Found in ca. 1985

Col. Antonio Trigo (Mataró)


 

RM2461   Natrolite

Cape Grim, Circular Head, Tasmania, Australia

Globular aggregate of prismatic natrolite crystals, with well defined terminal faces. It is disposed very aerially on the matrix. Specimens on matrix are unusual. It comes from a locality well known for its zeolites. Nowadays this Cape Grim area is restricted access due to wind turbines field. From the former J. Astor Collection (Barcelona).


Size: 3.5 x 3.2 x 2.8 cm.
Main crystal: 1.5 cm. aggr.
Found in ca. 1983.

RM2077   Stichtite with serpentine

Tunnel Hill Quarry, Serpentine Hill, North Dundas, Zeehan district, Tasmania, Australia

Good sized specimen of stichite, very rich and aesthetic. It comes from the mining area in which the species has its Type Locality, in Tasmania. The brightness, the intense purple color, the waxy luster and the fibrous shape make it a quality piece. In a serpentinite matrix. A highly representative combination of this rare species. The stichtite is a rare hydrated carbonate of chromium and magnesium from the group of the hydrotalcite.


Size: 10.2 x 6 x 2.8 cm.

RM1718   Pyromorphite

Sylvester mine, Zeehan, West Coast, Tasmania, Australia

Rich group of intense green color pyromorphite crystals with color zoning. From a locality unusual in collections. With Joan Viñals label and analyzed.


Size: 9.5 x 4.5 x 4 cm.

Col. J.M. Manchion, Barcelona.
 

RM1390   Axinite-(Fe) with calcite and quartz

Colebrook Hill Mine, Colebrook Hill, Rosebery, Tasmania, Australia

If something I like about the world of selling minerals is to find specimens lost in the nooks of old collections. This sample is a case of this. It is an Australian piece, of good size, formed by a druse of ferro-axinite crystals, not very big, but with an excellent color and transparency. They are accompanied by calcite and curious milky quartz. The specimen comes from a locality located NW of Queenstown, Tasmania, a big skarn that was worked by their sulfides: pyrite, pyrrhotite, arsenopyrite, chalcopyrite. Under the calcite ferro-axinite appeared... But a long time ago.


Size: 9.8 x 8.0 x 7.0 cm.
Main crystal: 8 x 1 mm.

 

RM1207   Crocoite

Adelaide Mine, Dundas, Zeehan, Tasmania, Australia

Rich group of elongated prismatic crystals of crocoite with an intense orange to red color very characteristic for the species. Brilliant and partially covering the goethite and rocky matrix.


Size: 12.4 x 5.8 x 4.5 cm.
Main crystal: 18 x 3 mm.
