Miniere di Cogne, Cogne, Valle di Cogne, Valle d'Aosta, Italia
Old iron mines located above the Cogne village.
The most important mines are:
-Larcinaz / Larsinaz (1975-2025 m)
-Costa del Pino (2027 m)
-Colonna (2410 m)
-Liconi (2520 m)
The main exploited ore was magnetite of good quality for iron and steel industry from the Middle Ages to 1979..
In the Cogne area, magnetite mineralization occurs associated with different types of serpentinite (pseudomorphic, rodingitic and magnetite-rich serpentinites), which are also heterogeneous in terms of bulk chemical composition, mineral assemblage and mineral chemistry. The mineralization is hosted by a lizardite-, ±chrysotile-bearing serpentinite showing a pseudomorphic texture after oceanic peridotite. It contains fine-grained magnetite showing oscillatory zoning with Cr-poor cores (∼ 0.4 wt.% Cr2O3), which are surrounded by Cr-rich inner euhedral rims (up to 17.0 wt.% Cr2O3), mantled in turn by partially resorbed Cr-bearing outer rims (∼2.0 wt.% Cr2O3). In these rocks, lizardite, the primary serpentine phase, is partially overgrown by prograde antigorite, indicating that serpentinization occurred under relatively low-T conditions in a preorogenic (i.e., oceanic) setting, and was followed by an Alpine metamorphic re-equilibration. Rodingitic serpentinite and serpentinite rich in magnetite are composed of, in highly variable amounts, diopside (locally with inclusions of partially disordered graphite), calcite, magnetite, andradite/hydroandradite, prograde olivine, brucite and serpentine (mostly antigorite but also relict lizardite), with minor chlorite and accessory apatite. Magnetite content can be very high. In these rocks, magnetite is exceptionally Cr-poor (almost Cr-free).
