Age range: Quaternary Period (Q) — Quaternary Period (Q)
Lithological Description: Polymict deposit: comprises gravel, sand and clay depending on upslope source and distance from source. Poorly sorted and poorly stratified deposits formed mostly by solifluction and/or hillwash and soil creep. Essentially comprises sand and gravel, locally with lenses of silt, clay or peat and organic material. In the Bristol area: red or brown silt and stony clay with cobbles of hard rock, eg Carboniferous limestone or sandstone. Argillaceous frost-shattered rock debris either in-situ or soliflucted. Soliflucted deposits have variable sand/clay content. Older than "Head" and "Head 1" in the same map area. [Generic description].
