This report describes the geology of the 1:10 000 sheet TM 35 NE which
is included in the Eye (190) and Woodbridge (208) geological maps.
The area was f i r s t surveyed by W Whitaker and W H Dalton as part of
the Old Series One-Inch sheet 50 SE published in 1883. The primary
six-inch survey of the Snape area was made by J A Zalasiewicz in
1982-3 under the direction of D r W A Read as Programme Manager.
Uncoloured dyeline copies of the map can be obtained from the British
Geological Survey, Keyworth.
The sheet area lies some 10 Km north-east of Woodbridge, Suffolk.
Most of the ground is broadly f l a t and lies a t c 20-25 m OD. It is
underlain largely by Boulder Clay and given over to arable farming.
Boulder Clay is absent from the south-east of the area, where a broad
outcrop of Kesgrave Sands and Gravels largely coincides with
coniferous forest.
The south-eastwards flowing River Alde and its tributaries have
incised wide valleys in the central and northern parts of the area.
Kesgrave Sands and Gravels and the underlying Chillesford Sand crop
out in the valley sides, together with irregular masses of
Fluvio-Glacial Sand and Gravel and Boulder Clay. The wide f l a t valley
floors are underlain by freshwater and estuarine alluvium, and are
given over to arable farming with some pasture.
The major settlement is Snape, where The Maltings is now a well-known
concert hall. There are two smaller settlements, Tunstall and
Blaxhall, and a number of scattered farmsteads
