Buchite, Porcellanite

Piast mine heap, Piast Mine, Nowa Ruda, Kłodzko County, Lower Silesian Voivodeship, Poland

This is a thin section (normal light, binocular photo) of a composite pyrometamorphic formation sometimes called pyrometamorphic breccia. Most of the section is multi-color, very characteristic buchite with clearly seen vesicular texture. The white rock is porcellanite. The buchite is mainly composed of mullite, a spinel phase (yellow-orange ...

6.7 x 5.2 x 2.6 cm. Superb pink radial "sprays" of what was labeled as being pharmacolite are coating the underlying matrix from this former German locality (now in Poland). Mindat states that pharmacolite is not actually valid from this locality, so this is most likely alumohydrocalcite. The piece comes with an old label from Ward's Natural ...

A view from the heap

Piast mine heap, Piast Mine, Nowa Ruda, Kłodzko County, Lower Silesian Voivodeship, Poland

A view from the Piast plateau. This upper part releases quite a lot of heat coming from the internal fire. The white area is where some corundum was found. Behind it there are ground cracks with very minor sulfur and cryptohalite were found. These minerals crystallized directly from the coal fire gas phase (i.e., via condensation = desublimation).

Cryptohalite-bearing fumarole (now extinct)

A ground crack at the "Piast" mine heap plateau, with a fumarole containing white encrustations of condensate minerals: gypsum plus tiny amounts of cryptohalite (one of two natural modifications of ammonium hexafluorosilicate) and native sulfur. These fumaroles are now extinct.
