About the Cover

Cover photo by authors: Kinderscout Grit, Holybank Quarry, Tintwhistle [SK 026 976].

This quarry section exposes the delta top deposits of the Kinderscout Grit. The characteristics of these sandstones suggest that they represent large-scale fluvial channels. Some of the main geometries are trough cross bedding, which represents the migration of sinuous crested-dune forms parallel to the current direction, and multiple erosion surfaces. The lower part of the quarry is dominated by giant foresets, up to 20 metres high that are truncated by a prominent erosion surface. These foresets represent very large-scale bar forms that developed within the channel system and indicate that the channel was at least 20 metres deep. The range of sedimentary structures, the grain-size variations and geometry of the sand body suggest that the Kinderscout Grit represents a multi-storey, multilateral braided river of comparable size to the present-day Brahmaputra.
