Italy,
Trentino Alto Adige, Bolzano prov., minerals from fluorite mines
In this page some fluorite
specimens, coming from veins usually located (a) in the contact areas
between Brixner granite (granito di Bressanone) e Brixner quartz
phyllite (fillade quarzifera di Bressanone) (b) in the large Atesina
porphyry platform

Fluorite
Cubic XX, max edge 1.4cm, on a bed of calcite. Some XX are
semitransparent with white phantoms inside, other are transparent and
glassy. On the right and the back there are some bigger, less evident, cubic XX of light green
fluorite. The yellow calcite is posted on the green fluorite, as
it is possible to see in the 2nd photo. This is a fluorite mine (34 Km
north of Bolzano) that
started as a silver mine in the 17th century (Ag-rich galena), then sphalerite was mined; it is famous worldwide for optical fluorite. This
locality it is not to be confused with Corvara in Val Badia

Fluorite
Cubic XX, yellowish and semitransparent, edge up to 1.8 cm. Upper
side of XX in covered by pale pink baryte (see the 3rd photo),
and there are some malformed small cubic XX of galena. From old mines (Monte Quaria, Case a Prato) in this locality, not well known,
south of Bolzano and near Catinaccio and Latemar. I have seen similar pieces labelled from Prestavel mine
(Fiemme Valley, Trento prov.) but I have been told that in this mine
there were the dressing plants for the minerals transported from Nova Ponente
