Examples

- Depositional environments in ancient sediments are recognised using a combination of sedimentary facies, facies associations, sedimentary structures and fossils, particularly trace fossil assemblages, as they indicate the environment in which they lived.
- His reconstructions of Wealden palaeography and depositional environments have been based on meticulous examination and analysis of faecies changes, sedimentary structures and petrology combined with a study of modern deltaic and littoral sedimentation.
