Analysis Of Heavy Minerals In Arenaceous Lutites From The Northern Canada Basin, Arctic Ocean, Kim Zauderer
OES Theses and Dissertations
Heavy minerals from arenaceous lutites in three widely spaced cores from the northern Canada Basin were analyzed for the first time to determine the provenance of these sediments. The abundant minerals (sp. gr. == 2.70) in decreasing order for most samples were detrital carbonate, micas, clinoamphibole, clinopyroxene, garnet, epidote, tourmaline, and chlorite. The majority of pyroxene grains were etched. Sedimentary sources dominated and metamorphic and igneous sources were important but secondary. The northern Canada Arctic Archipelago and northern Greenland is proposed as the provenance for the heavy minerals in the arenaceous lutites for at least the past three million years. …
