Thompson (Thompson Nickel Belt)
Manitoba (Thompson Nickel Belt), Canada
Magmatic (Ni-Cu-PGE, carbonatites)Ni (Cu, Co)
- Type
- Magmatic Ni sulphides associated with ultramafic rocks (Palaeoproterozoic)
Thompson Nickel Belt, on the margin of the Superior craton: nickel sulphides formed by interaction of ultramafic magmas with crustal sulphides, later reworked (Bleeker and Macek, 1996, cited by Elliott and Steele, 2017). Indicative coordinates (town of Thompson).
