In this page, the photos of minerals (different from fluorite: see the Dossena fluorite page) from the old mines of Paglio Pignolino, near the village of Dossena) . The pieces from this mine are often coated by a white powder that is a mixture of hydrozincite, smithsonite and hemimorphite, called calamina (this is also the old name of smithsonite).

 

Aragonite
Stalactitic formation of aragonite
8x3.5cm
Cantiere Corone, Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.1178

 

Bournonite
Aggregate of malformed XX, 3x5 cm wide. It is on calcite partially dissolved with acid
8x5cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.1176

Calcite
Combination of big scalenohedron, without matrix. This piece was found, together with some others I have in my collection, in a ore assay near the mine, full of clay and mould and this explains the lack of matrix
15.5x9cm
Cantiere Corone, Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.968

 

Calcite
Big rhombohedron, partially covered by microcrystalline encrustation of hydrozincite; there are some hemimorphite small XX
6.5x4.5cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.1055

Calcite
 Rhombohedron 1.7 cm high, replaced by smithsonite apparently mixed with other powdery alteration minerals. The pseudomorphosis is clearer in the 2nd photo, where it is possible to see the pinkish coating
12x7cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.1144

Another photo: bigger and different view

 

Calcite
Group of rhombs, edge up to 2.5cm, semi-transparent; there is a partial coating of hydrozincite. On the back there are some small XX of optical fluorite, colorless and transparent
14x9cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.1056

Calcite
Combinations of rhombs, edge up to 3.4cm; there are some hemimorphite XX
6.5x6cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.1057

Calcite
A detail of a bigger piece, with calcite XX (edge up to 1.7cm) partially replaced and covered by white smithsonite (a bigger view in the 2nd photo) and hydrozincite (hydrozincite is an alteration product also of smithsonite). In the last photo it is possible to see the reticulated shape of hydrozincite that has replaced the calcite XX edges
15.5x9cm

Specimen n.1058

Cerussite
Twinned formation, with the usual V shape, encrusted by a reddish coat, on a small portion of fluorite
4.8x4.5cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.467

Another photo: bigger and different view

 

 

Cerussite
"V" formation of cerussite, 1.8x1.5cm wide, on matrix
6x5cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.324

Cerussite
Twinned formation, 3x2.3 cm wide
4.5x2.5cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.1241

 

 

Cerussite
Twinned formation of cerussite, unfortunately non entire, posted on a matrix of gypsum, probably dissolved. On the base there are some cubic fluorite XX
5x4cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.801

Smithsonite
A former scalenohedron of calcite has been completely replaced by smithsonite, to obtain a malformed new X. The former X is partially empty, calcite has been dissolved (2nd photo)
10x10cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.764

Another photo: back of piece

 

Smithsonite
Large piece (see the 2nd photo) showing pseudomorphosis of smithsonite after calcite. In the 3rd photo it is possible to see details on the the calcite cast
28x18cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.686

Another photo: entire piece
Another photo: a view on former calcite
Another photo: detail of reddish part

 

 

Smithsonite
Another pseudomorphosis: the yellow color is due to greenockite inclusion
5x3.5cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.273

 

Smithsonite
This piece is made of compact fluorite veins embedded in the rock. The surface of fluorite is replaced my microcrystalline smithsonite, in a globular appearance with pearly reflections. In evidence a corner of a former fluorite cubic X
10x10cm
Paglio Pignolino, Dossena, Bergamo. Italy
Specimen n.1165

Another photo: entire piece

 

Smithsonite
Small XX of green smithsonite, filling cavities in the mineralized rock. There is a small portion with earthy coating of yellow greenockite (3rd photo)
