Genetically related lithosomes constitute the integrated response of a sedimentary environment to the depositional process. Sedimentary environments are therefore integral parts of the hierarchy of sedimentation elements, since they consist of combinations of lower ranking sedimentation elements by which they can be identified. Palaeo-environmental analysis makes use of diagnostic combinations of these in many different forms, ranging from the superposition of characteristic deflections in geophysical logs to the regional changes observed in a fossil assemblage. In some cases palaeo-environmental conclusions can be reached only after the careful study of many different aspects of a vertical profile, while in others the genetically based depositional assessment becomes part of the logging process, whereby either outcrops, bore cores, geophysical signals or a combination of these are used (Fisher and McGowen 1967; Weber et al. 1984; Hamilton and Beckett 1984; Hamilton 1986).
