Reports on the formation of carbonate modules and slabs in late Holocene shelly terrigenous deposits of the modern Fraser River delta in British Columbia close to the seafloor by precipitation from saline pore waters of mainly fibrous to bladed crystals of high-magnesium (Mg) calcite cement as coalescing isopachous crusts on grains. Indication that the bulk of the carbonate carbon was derived from the microbiological degradation of organic matter in the deltaic deposits during shallow burial; Possibility that methane-derived Mg-calcite is the major submarine cement in several other modern occurrences of lithified shallow-water terrigenous sands and muds at non-tropical latitudes. |
