| 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: |

| Thickness: |
