Abstract

The coal-bearing sediments of the Port Hood Formation (Westphalian) of Cape Linzee, Cape Breton Island, are entirely of continental origin. Fining-upward sandstones, between 8 and 17 m thick, appear to have been deposited by meandering rivers. Thick ripple laminated units suggest that some channels were abandoned by chute cut-off. Sandstone units less than 5 m thick, and which lack a basal erosion surface, are interpreted as crevasse splay deposits. These appear to have built out into both lakes and vegetated, swampy floodplains. Lakes probably formed by channel abandonment and by subsidence of the floodplain below the water table. Without a knowledge of the regional sedimentologie relationships, it may be difficult to discriminate between the deposits of a continental floodplain with extensive lacustrine development and the deposits of an upper delta plain.
