Green infrastructure and open environments: London’s foundations: protecting the geodiversity of the capital, Supplementary Planning Guidance, published by the Mayor of London in March 2012, defines allochthonous as: ‘Pertaining to materials, particularly rock masses, that formed somewhere other than their present location, and were transported by fault movements, large-scale gravity sliding, or similar processes. Autochthonous material, in contrast, formed in its present location. Landslides can result in large masses of allochthonous rock, which typically can be distinguished from autochthonous rocks on the basis of their difference in composition. Faults and folds can also separate allochthons from autochthons.’
