Objective(s): The Devonian patch reefs of Mercy Bay, Banks Island NWT are important as an example of fossil coral reefs that grew in a siliciclastic environment on a broad continental shelf. These reefs may also be able to provide insight into the nature of a reef ecosystem immediately before a time of global reef collapse. These reefs have been described qualitatively, but have not been studies using modern paleoecological methods. The current study will re-examine the detailed structure, sedimentology, and paleoecology of these reefs. The structure and composition of the Mercy Bay reefs will be compared with lower Middle Devonian reefs on the Princess Royal Islands and the adjacent western shore of Victoria Island, Middle Devonian reefs of southern Canada, and modern reefs on siliciclastic shelves.
