Rockslide Formation (original) (raw)

The Rockslide Formation is a geologic formation in Northwest Territories. It preserves fossils dating back to the Drumian (Plagiura-Pogiella to Bolaspidella Zone). It was deposited in deep water on a reasonably distal slope; it contains carbonates, debris flows and siliciclastic siltstones, the latter being the fossil bearing horizons. It also contains deep-water microbial reefs.
