Abstract
Bottom sediments of the northern British Columbia continental shelf contain, on average, 10% of heavy minerals by weight within the dominant sand fraction. Anomalous concentrations occur within selected sand samples from Queen Charlotte Sound (> 25%) and Hecate Strait (> 18%). The heavy mineral suite here is dominated by amphibole and the titanium minerals ilmenite, sphene and titaniferous magnetite. Dynamic modelling of the present oceanographic and sedimentary environment in Queen Charlotte Sound suggests that the anomalous offshore concentrations of heavy minerals result from continuous differential sorting during extreme yearly storms. The deposits are not considered to be relict.
