VALLEY SEDIMENTS OF THE CHELMER AND SANDON BROOK.

Author(s): P Murphy, T J Wilkinson

The alluvial deposits of the rivers Chelmer and Blackwater and their tributaries are discussed by Bristow (1985, 69), who distinguishes an upper predominantly clayey unit and a lower gravelly unit, termed the sub-alluvial gravels. Deposition of the gravels is considered to have begun in the Devensian, whilst the upper finer-textured sediments are thought to have formed during the Flandrian , though until recently no direct dating evidence has ben available.
