| Abstract | Reconnaissance section FNA16A documents a well-exposed section through the Neoproterozoic Katherine Group and Cambrian Nainlin Formation along a creek in southwest Sans Sault Rapids map area (NTS 106H),
northern Mackenzie Mountains, Northwest Territories. It provides a useful control point for the character and thickness of units not typically well-exposed in the northern Mackenzie Mountains, and will assist in the mapping of these units. The
described units include: the uppermost Tsezotene Formation (interbedded mudrock, dolostone, and sandstone), the Eduni Formation (sandstone dominated), Tawu Formation (interbedded mudrock and sandstone), the Grafe River Formation (sandstone
dominated), the Etagochile Formation (mudrock, sandstone, and dolostone), the Shattered Range Formation (sandstone dominated), the Nainlin Formation (red-weathering mudrocks and minor sandstone), and the lowermost beds of the Franklin Mountain
Formation (dolostone). Identification of the recessive intervals within Tawu and Etagochile formations is important for the mapping of the formations of the lower Katherine Group. |
| Summary | (Plain Language Summary, not published)
This report documents observations of the Neoproterozoic Katherine Group at a well exposed section in the northern Mackenzie Mountains. The section
provides a point of comparison to assist bedrock mapping. Features visible in the section have implications for the recognition of the formation-level subdivisions of the Katherine Group in northern Mackenzie Mountains. |
