Maps showing three typical examples of comparable geometric relationships between major steeply dipping deformation zones, occurrence of metamorphic supracrustals, and mineralisation. (a) Greenschist-facies Archaean gold-bearing southern Abitibi (Quebec), (b) Greenschist to lower amphibolite facies Archaean Antimony-bearing Murchison belt (South Africa). (c) High-grade amphibolite facies Paleoproterozoic Nickel-bearing Thompson Belt (Manitoba, Canada). Modified after Gapais et al., 2014. See text for further explanations.
