Rodingite dykes in magnetite-bearing antigorite serpentinite with lenses and veins rich in reddish titanclinohumite, diopside, and olivine (forsterite). The main rodingite outcrops are located at the base of the Monte Rosso di Verra north face and WSW of Passo Superiore di Bettolina. Other well-known outcrops are located at the western foot of Monte Rosso di Verra.
The first record on rodingite minerals from the Monte Rosso di Verra area was published by Zambonini (1903), who studied some epidote crystals (collected by the geologist Vittorio Novarese) and also mentioned the presence of garnet, diopside, magnetite, chlorite, and amphibole to the north of Monte Rosso di Verra, in the proximity of the pass nowadays known as Passo Superiore di Bettolina or Obre Betlinoforkò, but at that time unnamed on the I.G.M. map and for which Novarese coined the name Passo di Bettolina Nord.
Probably, the epidote crystals on serpentinite, generically reported from the area between the alpine pastures of Bettolina (Lys Valley) and Verra (Ayas Valley) in Barelli (1835), comes from this occurrence.
Rodingite minerals have been later studied by Boeris (1909) and Carpanese (1925a, 1925b; 1929, 1932a, 1932b). Garnets are terms of andradite-grossular series, tipically red-orange to brown in colour, for which Carpanese (1932a) gave an average composition of Grs66.31 And28.11; garnets with higher content in grossular (honey-yellow to pale yellow-green and rarely almost white or colorless) have also been found. Yellow-greenish epidote, pale green and brown vesuvianite, and colurless diopside crystals are other typical minerals of these rodingite bodies.
Furthermore, andradite crystals, as yellow topazolite or green demantoid, titanclinohumite (Ti-bearing hydroxylclinohumite) nodules, and asbestiform amphiboles are found in serpentinite, outside of the rodingite bodies (Boeris, 1910; Carpanese, 1933a; De Michele, 1972).
