Abstract
The Quaternary geology component of the Central Baffin Project was part of a program designed to provide information fore resource development. This report provides a summary of surface materials and glacial history in four areas: Longstaff Bluff, Rushmore Bay, Astarte River and Flint Lake. The results of this study affect the interpretation of geochemical data derived from lake sediment sampling and till sampling. Ice-flow indicators establish that materials have been transported south and west of their sources areas by glaciers. Glacial materials below an elevation of 100 m have been admixed with, or overlain by, postglacial marine sediments. Some postglacial weathering of sulphide minerals in till and bedrock has occurred. Marble-derived carbonate in till in some areas may act as a buffer to limit sulphide leaching, and may explain some geochemical anomalies.
