Characterization of a ~1 billion year old carbonate ramp in the Brock Inlier, Arctic Canada
The Brock Inlier, Northwest Territories, comprises carbonate and siliciclastic sedimentary rocks of the early Neoproterozoic (~1000-720 Ma) Shaler Supergroup. Strata were deposited in a large embayment (Amundsen Basin), an epeiric sea within the supercontinent Rodinia. Strata in the Brock Inlier cor...
