Geology of the Eastern Cobequid Highlands, Nova Scotia

The Cobequid Highlands of Nova Scotia lie within the Avalon composite terrane of the Appalachian Orogen. This report presents a description & interpretation of the field, structural, and laboratory studies of pre-Carboniferous rocks of the eastern part of the Highlands based on mapping at 1:10,000 scale. It includes information on the Precambrian & Palaeozoic sedimentary, volcanic, & plutonic rocks; geochemistry of selected rocks; uranium-lead age determinations; and structural geology, including deformation histories & faults. Correlations with rocks in the Antigonish Highlands are also discussed.
