Mineralogical locations
of Piedmont

Right Ala Valley
Neir Roch-Pian della Mussa-Balme (TO)

This location is easily mineralogical visibile from Grange della Mussa, shaped like a giant cake stand out its darkish and walls smoothed by the action of glaciers.

We are located at Pian della Mussa at the foot of the head of the Valley of Ala, the Alpine environment surrounding us is of extraordinary beauty.

It is one of the classic Valley mineralogical Ala already known since 1700 and later exploited with a succession of various concessions.

In 1873 the Jervis, in his book SUBTERRANEAN treasures of Italy, signaled to the Black Rock, a small protrusion above the Alpe di Mussa, extraordinarily beautiful minerals such as topazolite with large crystals from the colors ranging from yellow to green.

You can see the base of two landfills and Neil Roch very close between them that correspond to primary deposits overlying wall.

Other veins are present at Roch rodingite Neil over the ridge that continues in the direction of Arnas and boulders are scattered in the nearby forest of conifers.

Currently several reports indicate the private property of the Fund and the ban on the collection of minerals.


The minerals

Calcite, chlorite, epidote, do, mussite, magnetite, idrossiclinohummite, topazolite, vesuvianite.


My heartfelt thanks to Istituto Geografico Militare in Florence that has made available the cartography of the area treated.
