Soar Valley Formation

Computer Code: SOARV Preferred Map Code: notEntered
Status Code: Full
Age range: Pleistocene Epoch (QP) — Holocene Epoch (QH)
Lithological Description: Mainly post-Anglian fluvial terrace and alluvial deposits of the River Soar of Leicestershire and those of its tributaries such as the Wreake, but excluding Anglian/pre Anglian deposits of the so-called Proto-Soar or Bytham River. Mainly sand, gravel and mud; divided (in type area) into six principal "terrace" members (Eagle Moor, Knighton, Birstall, Wanlip, Syston, and Hemington members), plus Holocene alluvium (the Soar Member of Bowen, 1999). Includes contemporaneous head, colluvium and soil deposits. Gravel is generally dominated by "Bunter" pebbles and flints in roughly equal proportions, plus other components including Charnian material.
Definition of Lower Boundary: Unconformable, commonly channelled base on Anglian glacial deposits (Wolston Formation) or on pre-Quaternary bedrock.
Definition of Upper Boundary: Ground surface.
Thickness: 0 to c.10m
Geographical Limits: Catchment of the modern Soar (including Wreake).
Parent Unit: Trent-Witham Catchments Subgroup (TRWCA)
