Calcite veins in serpentinite blocks.
Ti-bearing hydroxylclinohumite nodules (up to 16 x 22 x 8 cm) in association with forsterite, clinochlore, and magnetite have been found along the eastern slope of Braccia Mt., at an elevation of about 2000 m, above Alpe Girosso.
An occurrence of brown or blackish perovskite crystals is known to the south-west of Alpe Girosso Superiore, at an elevation of about 2450 m.
GPS coordinates are for Alpe Girosso Superiore (the Alpe Girosso Inferiore is a little to the east).
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).
