| Abstract | This report documents the Lower to Middle Cambrian Mount Clark, Mount Cap, and Saline River formations in the Carcajou and Norman ranges, western mainland Northwest Territories. The "Bearpaw Creek"
section (section 1), exposes the sandstone-dominated uppermost Abraham Plains Formation (Katherine Group; ~2.4 m measured), unconformably overlain by a complete section of the Cambrian sandstone-dominated Mount Clark (~11.6 m measured), dolostone and
dolomitic-sandstone-dominated Mount Cap (~23.2 m measured) and gypsite-dominated Saline River formations (~66.7 m measured), and lowermost carbonate-dominated Cambrian-Ordovician Franklin Mountain Formation. Dodo Creek sections A and B (section 2A
and B), consist of incomplete, overlapping sections of the Mount Cap Formation (section A ~35.5 m measured; section B ~28.8 m measured). The Norman Range section (section 3) is an almost complete section of the Saline River Formation (~182.4 m
measured), which is conformably overlain by the lowermost units of the Franklin Mountain Formation. |
| Summary | (Plain Language Summary, not published)
This report documents the rock types present in two measured sections through Cambrian-aged formations in the Mackenzie Mountains. The formations are,
from oldest to youngest, Mount Clark Formation, Mount Cap Formation, and Saline River Formation. Mount Clark Formation is dominated by sandstone, Mount Cap Formation consists mainly of shale and carbonate rocks, and Saline River Formation consists
mainly of shale and gypsum. The ancient environments that deposited these rocks are discussed. |
