Abstract

this paper documents a previously unrecorded type of leaf deposit, comprising essentially monospecific linear accumulations of Colophospermum mopane leaves on a point bar of the ehemeral Hoanib River, NW Namibia. In these "Leaf jams", leaf laminae stand on edge, orientated more-or-less normal to bedding. Leaf-jams, whisch formed upstream of cobbles, clumps of grass and sticks wedged against the former two, were orientated subparallel to the adjacent meandering river-bed, such that over the 40 m of their occurence, their mean azimuth changed by 59° anticlockwise downstream.
