Geological notes and local details for 1:10 000 sheet TM 35 SE (Snape) : part of 1:50 000 sheets 190 (Eye) and 208 (Woodbridge)

Abstract

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
