AbstractMapping was carried out in parallel with detailed stratigraphic and sedimentological studies mainly focused along the Hornaday River, Northwest Territories and its tributaries, during a three-week period in late July and August of 2015. The map covers the southern part of the Brock Inlier, an uplifted, mildly folded and faulted region of mainly Mesoproterozoic to Neoproterozoic (Stenian-Tonian) sedimentary rocks of the Shaler Supergroup and Neoproterozoic (Cryogenian) mafic intrusive rocks, surrounded and draped by early Paleozoic (Cambrian-Devonian) and Cretaceous sedimentary rocks. The geological interpretation was aided by 2D and 3D visualization of moderate-resolution satellite imagery (Spot 5 and RapidEye-5m panchromatic).
Summary(Plain Language Summary, not published)
Bedrock geology of the southern Brock Inlier is intended to be an update of GSC Preliminary Map 5-1969 by D.G. Cook and J.D. Aitken (1969). Highlights new stratigraphic units of the Proterozoic Shaler Supergroup and incorporates subsequent mapping by Jones et al., 1992. Much of the geological interpretation was aided by 3D visualization of moderate-resolution satellite imagery (RapidEye-5m panchromatic).
