Redmond Formation (Canada)

The Redmond Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the mid-Cretaceous (Cenomanian). It was a thin (up to 1.5 metres (4.9 ft) thick) and restricted unit traced for 152 metres (499 ft) in a single mine (Redmond No. 1) in Labrador, overlying Paleoproterozoic rocks, with large amounts of rubble, probably as a result of graben subsidence within the Labrador trough. Argillite facies within the formation have produced a diverse flora and insect assemblage.^[1]
