Computer Code: WAVV Preferred Map Code: notEntered
Status Code: Full
Age range: Mid Pleistocene Epoch (QPM) — Holocene Epoch (QH)
Lithological Description: The formation encompasses the fluvial , lacustrine and organic deposits of the River Waveney and its tributaries. It includes floodplain alluvium and a restricted development of river terrace deposits. The floodplain alluvium comprises soft clays, silts and fine-grained sands, with bodies of peat, overlying fine- to coarse-grained sands and gravels. River terrace deposits are largely gravel and sand. The gravels are dominated by subangular to rounded flint, including large cobbles, also rounded pebbles of quartz and quartzite and a little chalk.
Definition of Lower Boundary: Unconformable upon glacial and solifluction deposits and upon Crag Group and Chalk Group bedrock.
Definition of Upper Boundary: Surface.
Thickness: c.5m
Geographical Limits: Valley of River Waveney and its tributaries, from west of Diss, Suffolk, to its junction with the River Yare northwest of Lowestoft.
Parent Unit: Yare Catchments Subgroup (YCAT)
