Braccia Mt., Chiesa in Valmalenco, Malenco Valley, Valtellina, Sondrio Province, Lombardy, Italy

This page is currently not sponsored. Click here to sponsor this page.
 
Name(s) in local language(s): Monte Braccia, Chiesa in Valmalenco, Valmalenco (Val Malenco), Valtellina, Sondrio, Lombardia, Italia
 
Calcite veins in serpentinite blocks mainly on the eastern slope of Braccia Mt., at an elevation of about 2000 m to the south of the upper Füraas valley, but also in various other places around Braccia Mt.

Honey-yellow to blackish perovskite crystals from the eastern slope of Braccia Mt. were described by Boeris (1911).



Note on “Ti-bearing clinohumite, titanclinohumite”:
according to the analyses performed, this mineral in the Malenco valley serpentinite is practically fluorine-free (Trommsdorff and Evans, 1980). Therefore, after institution of the new species hydroxylclinohumite in 1999, all records of “titanclinohumite” in the antecedent literature and specimens preserved in public and private collections consequently labelled are now Ti-bearing hydroxylclinohumite (Bedognè et al., 2006).
