AbstractIt is not possible to discriminate between single and multiple cycle stratigraphic models for the Archean Kaminak Group on the basis of fieldwork alone. However, facies associations in volcano-sedimentary rocks suggest that parts of the belt formed in an intra-arc depositional environment. In the Kaminak Group, regional deformation and metamorphism are Late Archean in age and have been influenced by the emplacement of major plutons. Most silicification and stratigraphically controlled carbonatization predates regional deformation. Some carbonatization and most sericitization is structurally controlled. The Mackenzie Lake sediments (sensu lato) represent two sequences: a Kaminak Group basement, and a cover of younger quartz arenites and conglomerates (Mackenzie Lake sediments sensu stricto). The Paleoproterozoic Hurwitz Group sits unconformably on a basement of Archean granitoids and Kaminak Group volcanic rocks. Paleoproterozoic reworking is confined to discontinuous chlorite alteration and quartz veining, with local cleavage, adjacent to the Hurwitz Group.
