WebJan 1, 2002 · The Hunstanton Till, which occurs in the northwest of the county, was formed during Late Devensian times. The tills of Holderness were deposited during the Wolstonian (Basement Till) and Devensian (Skipsea and Withernsea Tills) stages. The overlying Hessle Till is now regarded as a weathered derivative of the Devensian tills. Till is a form of glacial drift, which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is deposited directly by glaciers without being reworked by meltwater. Till is characteristically unsorted and unstratified, and is not usually consolidated. Most till consists predominantly of clay, silt, and sand, but with pebbles, cobbles, and boulders scattered through t… WebPermeability is the simplest measure of the producibility and injectivity of subsurface formations.
