Hand Specimen Description:

A hard, coarse, bioclastic limestone which is poorly sorted with a hackly fracture. Petworth Marble is the local name for 'Large Paludina' limestone which forms beds from 10-30cm thick composed largely of gastropods of globose species 'Viviparus Fluviorum', in a fine grained matrix that commonly contains ostracods and which may also be marly (Gallois 1993: 69 - 70).

General Comments:

'Sussex Marble' is a generic name for a number of very similar shelly limestones found at numerous locations along the Weald Clay in Sussex and Kent. The principal quarries were at Bethersden in Kent, and at Kirdford in Sussex. There were also the Gorlinger quarries near East Grinstead, and others at Petworth, Laughton between Lewes and Hailsham, and in Surrey at Charlwood, Outwood and Ewhurst (Clifton-Taylor & Simmons 1987: 178 -9).
