Archean Basement

A thin formation of folded mafic flows resting unconformably on Archean basement is informally named the Spi Lake basalt. Stratigraphic, structural, and textural evidence suggests that these lavas were probably fed from a diabase dike swarm dated at 2250+ m.y. by the Geological Survey of Canada. The Spi Lake basalt is overlain by conglomerate that may represent the base of the Hurwitz Group.

Hurwitz Group

Decimetric to metric domal stromatolites with constituent ministromatolites characterize reddish, 13C-enriched dolostones in the Watterson Formation of the Quartzite Lake area west of Hudson Bay. They provide paleontologic support for a correlation with the only other known early Paleoproterozoic stromatolite occurrences in North America: the Kona Formation of Michigan, and the Nash Formation in southern Wyoming. They also are similar to stromatolites in probable coeval Jatulian carbonates in Karelia on the Baltic Shield, and possibly to stromatolites in the Hutuo Group in China.

A structural study of the Early Proterozoic Hurwitz Group has been carried out in the Tavani area, approximately 80 km southwest of Rankin Inlet, District of Keewatin, Northwest Territories. The Hurwitz Group, in the Tavani area, consists of orthoquartzites of the Kinga Formation (Whiterock Lake Member) and quartz-feldspar arenites and litharenites of the Tavani Formation. More localized lithologies include siltstone, sandstones, breccia, and shales beneath the Whiterock Lake Member and conglomerate, shales, and shale-clast breccias within the Tavani Formation.Open, northeast-trending folds dominate the Hurwitz Group, although overturned folds and easterly trending structures are developed locally. Later northwest-trending faults complicate the northeast-trending structural pattern. Three structural domains are defined: north of the Wilson River, the Whiterock Syncline, and the Last Lake belt. The interrelationship of folding and faulting creates distinctive patterns in each domain, though overall, folding is demonstrated to be a local response to basement faulting, including reactivation of Archean structures. An overall north–south compressive regime is envisaged in which heterogeneities in the Archean basement are responsible for local peculiarities.
