AbstractRecent work in the Melville Peninsula area of the Rae Craton provides new constraints on the lithotectonic framework of Archean supracrustal rocks and associated Archean intrusions, as well as Paleoproterozoic cover sequences. The region is subdivided into four lithologically distinctive crustal blocks that include from north to south: the Northern Granulite Block; the Prince Albert Block; on which lies the Penrhyn Group; and the Repulse Bay Block. The Prince Albert belt is redefined as a ca. 3.20 Ga to 2.77 Ga greenstone belt, much older than the Committee Bay belt to which it was historically linked and collectively named the Prince Albert Group. On the eastern side of the Peninsula, the Roche Bay greenstone belt appears to be linked - at least in age - to the Prince Albert belt. Penetrative Paleoproterozoic deformation can be confidently documented northwesterly to the Roche Bay greenstone belt. Beyond this, it is less well defined although the Folster Lake Formation suggests moderate deformation under upper-greenschist metamorphic conditions.
Summary(Plain Language Summary, not published)
This report presents a summary of the main advances made in the understanding of the bedrock geology evolution of Melville Peninsula in NST map sheets 47A and 47B, as part of field-based activities related to the GEM-Minerals Melville Peninsula project. It includes a summary of previous mapping and geoscience research completed in the area, as well as an outline of new airborne geophysical and regional geochemical surveys completed in the early stages of the project. Implications for mineral exploration are discussed.
