RM1367   Ilmenite with epidote

Arkaroola Bore, North Flinders Ranges, South Australia, Australia

This specimen is really interesting not only for the quality of the crystal but the locality it comes from. Few specimens are represented in collections. This sample shows a brilliant metallic luster and sharp faces and edges. Located in a gully, this locality consists of outcropping hydrothermally-altered and weathered Wooltana volcanics containing veins and pockets of zeolites, calcite and crystallised ilmenite.

Main crystal: 27 x 20 x 8 mm.



 

RM1623   Scholzite

Reaphook Hill, Martins Well, South Flinders Ranges, Flinders Ranges, South Australia, Australia

Very rich scholzite specimen, an unusual phosphate of Ca and Zn, with elongated prismatic crystals, transparence and brilliance. It comes from a classic Australian locality for the species as is the Martins Well area, about 40 miles SE as such indicates this old label. A zinc and phosphorus-rich deposit in dispirited breccia. It is as mined for a few years for mineral specimens (mostly scholzite).


Size: 6.4 x 4.4 x 3.2 cm.
Main crystal: 10 x 1 mm.

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.

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.

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.

 

RM2067   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 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: 8.7 x 7 x 2.6 cm.

RM629   Smoky quartz

Anderson's Gully (Anderson's Creek), Mooralla, Southern Grampians Shire, Victoria, Australia

Specimens of this Australian locality are uncommon in the maket, but their beauty makes them stand out from the smoky quartz samples. It is very curious how these specimens nodules are found into rhyolitic matrix geodes called "thundereggs"; this vugs are usually covered by small milky quartz crystals, some amethyst... They are in themselves a treasure of Nature. In this specimen we offer we see a parallel growth, probably scepter, crossed with some crystals, one doubly terminated. Excellent transparency and smoky color zoning. On a small matrix. A very aesthetic and elegant piece.


Size: 4,5 x 3,4 x 3,0 cm.
Main crystal: 4,2 x 2,7 cm.

It is very curious how these specimens nodules are found into rhyolitic matrix geodes called "thundereggs"; this vugs are usually covered by small milky quartz crystals, some amethyst...

Specimens from this Australian mine are unusual today. In this sample we have a group of azurite crystals pseudomorphized by malachite, preserving very well defined faces and edges. They are disposed on a goethite matrix partially coated with malachite, chrysocolla and small yellow rystals of wulfenite.

RM2075   Dravite

Yinnietharra station, Yinnietharra, Upper Gascoyne Shire, Western Australia, Australia

Dravite crystals of Yinnietharra are a classic of the world mineralogy. Today, they can only be obtained from old collections that were fortunate enough to be formed when the mines were worked. This specimen shows us a group of doubly terminated dravite crystals, with very well defined faces and edges, bright and with the characteristic color of toasted honey. They are accompanied by muscovite.
Mining for muscovite used in the electrical industry occurred on Yinnietharra station at several sites between 1922 and 1946, beryl and columbite from 1942 to 1965, and gem specimen mining after this till around 1990. Minor rare earth, uranium bearing and lithium minerals are present but have never been mined to any extent. No mining on the field has been large scale.


Size: 5.8 x 4.6 x 4 cm.
Main crystal: 5.3 x 3.3 cm.
Found in ±1980.

RM1875   Awaruite

Awarua Bay, Gorge River, South Westland, South Island, New Zealand

This placer mining sample is from the Type Locality for the species. Under the loupe you can see several small nuggets of this alloy, accompanied by several black magnetite (octahedron), epidote... Awaruite is natural iron-nickel alloy with compositions within Ni3Fe-Ni2Fe range. Some of these nuggets have been analyzed by SEM-EDS and show a near perfect Fe:Ni 1:3 (see details attached).

"Awaruite was first described by Skey (1885) as constituting a sample of heavy black sand given by alluvial miners to the Government Warden of the Jackson's Bay District, South Island, New Zealand". From Skey, W. (1885), Trans. N.Z. Inst. 18:401-2.
