Russian Fluorite

The following are an interesting group of rare species found at the 2002 Munich Show.

This specimen of dolomite has crystals of hematite stained calcite upon which are deposited crystal
sprays of talmessite to 4 mm across.  Talmessite is a hydrated arsenate of calcium and magnesium.

This specimen of dolomite has crystals of hematite stained calcite upon which are deposited crystal
sprays of talmessite to 5 mm across.  Talmessite is a hydrated arsenate of calcium and magnesium.

Bladed crystals of calcite are coated and partially replaced by 0.5mm crystals of barrerite. Barrerite is a rare zeolite
found up till now only in tidal zones where sea water could react upon other zeolite species.

This specimen of calcareous matrix has abundant blebs of botryogen.  Botryogen is a hydrous sulfate of iron and magnesium.

Exceptionally rich specimen of voltaite (whitish crystalline crust and specks) on crystals of brown
szomolnokite.  Both species are sulfates and both contain iron.  Voltaite also contains potassium.

This specimen has an exposed vug with crystals of blusih green fluorite to 0.3 cm across and a crystal of burbankite.
Burbankite is a very rare carbonate species with the formula: (Na,Ca)3(Sr,Ba,Ce)3(CO3)5.
The crystal is 2 mm across and it also fluorescent under W UV light.

This specimen has abundant crystals of kosnarite to 2 mm across.  This is a quantum leap in size for the species.
Kosnarite is a phosphate of potassium and zirconium  and is weakly fluorescent greenish yellow under SW UV light.

Kosnarite is a phosphate of potassium and zirconium and is weakly fluorescent greenish yellow under SW UV light.

This specimen has abundant crystals of kosnarite to 1.5 mm across.  This is a quantum leap in size for the species.
Kosnarite is a phosphate of potassium and zirconium and is weakly fluorescent greenish yellow under SW UV light.

This old timer is 100% crylolite with one section of lustrous crystal faces.  Cryolite is a
fluoride of sodium and aluminum. The label glued on the specimen dates from 1871.

Close to a dozen sharp golden colored microlite octahedrons are perched on this specimen
which measures 8 X 5 X 5 cm.  The albite is almost gemmy and blue in color and is the main
matrix mineral.  There is ample green and watermelon tourmaline throughout the specimen with
some showing gemmy areas and some terminations.   This is an attractive combination
and association specimen with superb microlites up to 0.5 cm across.

Frozen crystals of davidite to 2 cm in length are found in this specimen of carbonatite. Davidite (La)
has a complex formula containing rare earth elements.  Its formula is: (La,Ce,Ca)(Y,U)(Ti,Fe)₂₀O₃₈
