...Richard N. Hiscott Abstract The Late Proterozoic Rock Harbour Group, as exposed on the Flat Islands, Placentia Bay, consists of a 700 m thick fining-upward sequence of deep-water conglomerates, pebbly sandstones, and thinly-bedded siltstones, capped by a chaotic olistostrome. This sequence rests...

Willey Abstract Three chemically distinct sediment types, as defined by factor analysis, occur in northern Placentia Bay; these correspond to the muds, the sands, and the amodal sediments (tills) in this area. Factors that control the sediment geochemistry in Placentia Bay are: the organic...
