Spoil from drain cleaning spread on an adjacent field contains traces of the bright blue mineral vivianite, a hydrated iron phosphate; formed here in Gault clay, the mineral would have been white while in situ but changes to this blue colour on exposure to the air. It is commonly associated with bone or fish remains in the sediment.
