Egginton Common Sand And Gravel Member

Computer Code: EGSG Preferred Map Code: symb
Status Code: Full
Age range: Pleistocene Epoch (QP) — Pleistocene Epoch (QP)
Lithological Description: Predominantly cold-phase sands and gravels that underlie the Egginton Common Terrace. Intensely cryoturbated, decalcified poorly sorted sand and gravel, dominated by rounded pebbles of "Bunter" quartz/quartzite (up to c.90%) with subordinate subangular flint (up to c.15%), Carboniferous chert, sandstone, etc., Fairly well developed and extensive terrace surface c.12-13m above the Trent/Dove floodplain in Type Area. Upper part locally includes a rubified paleosol (Hykeham Soil; Ipswichian). Correlated with the Borrowash Sand and Gravel Member (Derwent Valley Formation) and Burstall Sand and Gravel Member (Soar Valley Formation) and Balderton Sand and Gravel Member (Trent Valley Formation).
Definition of Lower Boundary: Unconformable, commonly channelled base, resting on pre-Quaternary bedrock.
Definition of Upper Boundary: Ground surface.
Thickness: 0-c.4.5m.
Geographical Limits: Occurs as outliers on north bank of Trent in type area (Sheet 141); thought to be present upstream, particularly on the north bank of the Dove downstream of Uttoxeter (Sheet 140) and probably elsewhere, (e.g. on the south bank of the Trent near Alrewas, Sheet 154) but extent uncertain pending resurvey.
Parent Unit: Trent Valley Formation (TRVA)
