RM2455   Balangeroite

Poggio San Vittore mine, Balangero, Torino, Piemonte, Italy

Really fine specimen for this rare species. The balangeroite is a magnesium, iron anfd manganese silicate, only found in a few places worldwide. The serpentine Poggio San Vittore quarry, which were the best samples has been found and it is the type locality for the species, is abandoned since 1990. The mineral usually appears included in the serpentine matrix and only few fibers are aerial. In this specimen, fibers are totally aerial and with a good length.


Size: 4.2 x 4 x 3.4 cm.
Main crystal: 3.2 cm.
Found in ca. 1985.

RM2221   Alurgite, Variety of Muscovite-2M1

Prabornaz mine, Saint-Marcel, Valle d'Aosta, Italy

Alurgite is a variety of purple muscovite. It was classified 1959 as an intermediate variety between leucophyllite and muscovite. A study of Knurr and Bailey (1986, online) showed that the alurgite, treated as muscovite-2M1 with Mn, contains trivalent manganese (in contrast to divalent Mn-containing "manganophyllite"). This specimen of good size shows us an aggregate of micaceous crystals, with an intense brilliance and good color, in a quartzite rocky matrix. A rare variety of muscovite.


Size: 10 x 8.5 x 6 cm.

 

RM2210   Baryte

Muscadroxius-Genna Tres Montis Mine, Silius, Sarrabus-Gerrei, Sardegna, Italy

Group of prismatic baryte crystals, doubly terminated and well defined, with good luster and transparency. They are disposed very aerially on the matrix. The history of the Silius mines begins in the first decades of the 20th century, particularly in 1916, when the first research permits were registered for the galena. It was in the early 1950s that the focus was on major fluorite outcrops and in 1953 the first company to obtain the mining concession for the exploitation of the rich fluors of fluorite and galena was created, the Mineraria Silius SpA, active until 2006.
