In fact, the NCC was dominated in the late Palaeoproterozoic by an extensional-tectonic regime, associated with the development of an aulacogen system, anorogenic magmatism (rapakivi granites, anorthosites, gabbros, granites and pegmatites), with the emplacement of large-scale mafic dyke swarms and with the uplift of the early metamorphic basement or the tectonothermal events of the retrogressive metamorphism.
