Figure F65. Hypothetical lithofacies motifs and facies succession for an upper slope location, such as Site U1421. Lithofacies are depicted by particle size variations with major facies types and sedimentary structures as described in the key. Associated columns are a descriptive summary for a facies, an inferred depositional environment, the major glacial systems tracts and bounding surfaces, and an inferred sediment accumulation rate. Modified from Powell and Cooper (2002). IRD = ice-rafted debris.
