Abstract
The surficial sediments in an area of similar to 4000 km super(2) in Hecate Strait, western Canada continental shelf, are composed predominantly of CaCO sub(3). The deposit is Holocene and forms a discontinuous unit consisting of coarse shell debris, typically < 1 m thick, overlying Tertiary bedrock. Carbonate sediments are largely restricted to water depths of < 50 m and are closely associated with rock and gravel substrates. The faunas yielding these sediments are predominantly bivalves, barnacles, and bryozoans. Radiocarbon dates on surficial material range from modern to 1500 yr B.P. Vigorous water circulation through tidal and wave action, combined with rocky or coarse-grained substrates in some areas, favors suspension-feeding biogenic carbonate producers. The presence of carbonates in Hecate Strait results from the glacial and postglacial history of the region.
