Book excerpt: This report outlines preliminary field results of bedrock mapping of a central Baffin Island study area that straddles the eastern segment of the Trans-Hudson Orogen. Orthogneiss in the Archean basement and rocks of the Paleoproterozoic Piling Group are described from the lowest to highest structural levels (Dewar Lakes, Flint Lake, Astarte River, Bravo Lake, Longstaff Bluff and related formations, the Cumberland Batholith, and the diabase dikes of the Franklin swarm). The final sections discuss deformation & metamorphism in the study area and briefly assess the potential for mineral deposits.
