Oxford Clay is a Jurassic marine sedimentary rock underlying much of southeast Englandmarker, from as far west as Dorsetmarker and as far north as Yorkshiremarker. The Oxford Clay is argillaceous (consists of clay) and is of Callovian to lower Oxfordian age.

Oxford Clay appears at the surface around Oxfordmarker, Peterboroughmarker and Weymouthmarker and is exposed in many quarries around these areas. The top of the Lower Oxford Clay shows a lithological change, where fissile shale changes to grey mudstone. The Middle and Upper Oxford Clays differ slightly, as they are separated by an argillaceous limestone in the South Midlands.

The Callovo-Oxfordian Clay also occurs in the Paris basin (Francemarker) and it is a potential host formation to dispose high-level radioactive waste in France.

Palaeontology

The Oxford Clay is well known for its rich fossil record of fish and invertebrates. Many of the fossils are well preserved, occasionally some are found exceptionally well preserved. Animals which lived in the Oxford Clay Sea include plesiosaurs, marine crocodiles, ichthyosaurs, cephalopods (such as belemnites), bivalves (such as Gryphaea), and a variety of gastropods.

Uses

Oxford Clay has a porous consistency and is soft and is often used in the making of roads. It is also the source of the Fletton stock brickmarker of which much of Londonmarker is built. For brick making, the Oxford Clay has the advantage of containing carbon which provides part of the fuel required in firing it so reducing the requirement for an external fuel source.
