| Abstract | This bedrock geological map is a product of the Geo-mapping for Energy and Minerals Program, Mackenzie Project. Mapping was carried out in parallel with detailed stratigraphic and sedimentological
studies mainly focused along the Hornaday and Brock rivers, Northwest Territories, and their tributaries during a three-week period in late July and August of 2014. The map covers the northern part of the Brock Inlier, an uplifted, mildly folded and
faulted region of mainly Mesoproterozoic (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 northern Brock Inlier is intended to be an update of GSC Preliminary Map 13-1970 by H.R. Balkwill and C.J. Yorath (1970).
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). |
