"Southampton Island, Nunavut, is situated between the Archean-dominated western Churchill Province and the Paleoproterozoic Baffin-Ungava segment of the Trans-Hudson Orogen. The island exposes a highland of Precambrian basement across much of its eastern half and flat-lying Paleozoic carbonate strata across its western half. The Precambrian basement complex consists predominantly of 3000–2700 Ma tonalitegranodiorite-granite gneiss, containing enclaves and inclusions of ca. 3 Ga maficultramafic-anorthositic plutonic rocks and lesser metasedimentary rocks. A smaller proportion of Paleoproterozoic gabbroic and granitic plutons also occurs. These rocks experienced profound amphibolite- to granulite-facies tectono-metamorphic reworking at 1880–1820 Ma, during the Trans-Hudson Orogen collision between the Rae and Superior cratons, resulting in their strongly foliated to gneissic character, followed by exhumation and cooling at 1790–1780 Ma"--Abstract.
