GA Guide Number 68

The guide to the Geology of London has chosen ten Itineraries from within the M25 to provide snapshots of the rocks underlying London. It aims to cover all the rock types that outcrop within the area. It describes several SSSI’s including Harefield, Charlton, Abbey Wood, and Quaternary sites in east London. Chalk is described from the magnificent quarry at Riddlesdown, Croydon as well as underground at Chislehurst and Pinner. Geomorphology walks, and the Geological Illustrations of Crystal Palace Park are also described. It is a multi-authored guide drawing on the best authority for the locations chosen.
