Flint Implements of Man from the Middle Glacial Gravel and the Chalky Boulder Clay of Suffolk
Published online by Cambridge University Press: 25 October 2013
Extract
The Middle Glacial Sands and Gravel which occur over such a large portion of East Anglia are somewhat difficult to explain, and various opinions have been put forward to account for them. In Suffolk they generally occur under the Chalky Boulder Clay, and in some parts of Norfolk between that deposit and the older Contorted Drift. In the neighbourhood of Ipswich these deposits generally rest upon Red Crag, and are covered by the Chalky Boulder Clay. They are best seen where pits have been sunk upon the plateau or where streams have cut into the plateau and exposed the various beds composing it.
Having discovered six years ago that the Middle Glacial Gravel is implementiferous, I have continually searched these deposits, and am led to the following views regarding them.
