Eagle Moor Sand And Gravel Member

Computer Code: EMSG 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 Eagle Moor Terrace. Dominated by rounded pebbles of "Bunter" quartz/quartzite with subordinate subangular flint (typically 25% in the Type Area), etc. Clayey and poorly sorted. In Type Area occurs as hill-top outliers falling from c.36m OD near Newark (c.25m above Trent floodplain) towards the Lincoln Gap, being at c.+32m OD at Eagle Moor and possibly descending more rapidly to the east. Outliers upstream in the Loughborough district 30m+ above Trent floodplain. Correlated with the Martin Sand and Gravel Member (Trent Valley Formation), east of the Lincoln Gap.
Definition of Lower Boundary: Unconformable, commonly channelled base, resting on pre-Quaternary bedrock or locally, east of Eagle Moor, on the Skellingthorpe Clay Member of the Wolston Formation.
Definition of Upper Boundary: Ground surface.
Thickness: 0 to c. 6m; typically c. 2 to 3m
Geographical Limits: Newark on Trent to Lincoln Gap (British Geological Survey sheets 113, 114, 126, 126; see Brandon and Sumbler, 1991, Figure 1) with probable outliers upstream in the Uttoxeter-Derby area (sheets 140, 141; included in Trent, Trent-Derwent and Soar Valley formations) and possibly elsewhere.
Parent Unit: Trent Valley Formation (TRVA)
