The origin of base metal indicator minerals from till and stream sediment samples: constraints from mineral chemical and S-Pb isotope geochemistry ...
Base metal indicator minerals recovered from till and stream sediment samples in the southern Northwest Territories were studied to determine their potential origins. Major and trace element geochemistry and S- and Pb-isotopes were used to determine whether these indicator minerals were derived from...
