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.

This volume is a collection of papers that resulted from a symposium on Recent and Ancient Nonmarine Depositional Environments which was held in Casper, Wyoming on June 3 to 7, 1979. The nineteen papers may be divided into: (1) a review of recent and ancient nonmarine modes, (2) alluvial fan and fluvial deposits, (3) lacustrine deposits, (4) eolian deposits. Knowledge of the physical, biological and chemical characteristics and depostional environments on nonmarine sedimentary deposits has increased significantly over the last decade. Correspondingly, there has also been an increase in our ability to apply this knowledge to the exploration and exploitation of contained energy resources and minerals.
