England and South Wales, south of a line from Pembroke in the west to Essex in the east in depths of up to a metre. Commercially useful deposits of about 2m to 4m thick are present in Kent, Hertfordshire and

out-wash sediments from glaciers were subject to windy dry periods. The exposed finer-grained sediments were picked up and transported by the wind and were deposited wherever the wind strength decreased.
175:, the brickearth is a flint-rich brown silty clay up to five metres thick, which occurs on the coastal plain. The brickearth is unfossiliferous but occasionally yields man-made flint implements.
49:, its composition being suitable for brick-making without additional material being added; unlike clay, its bricks can be hardened (fused) at lower temperatures, including in wood-fired kilns.
