Abstract
The main factors that lead to variation in detrital sediments are conceptually labelled as source material, which may consist of fresh rock and its weathered products, erosion, transportation, deposition and diagenesis; interpretive petrology depends upon the specification of petrographic properties which reflect the variation which arises from these six sources of variation.
If the measured properties are related to the factors in a two-dimensional classification the resulting model supplies a basis for expectations and a tool for deciding what properties to measure. A number of results already have been recorded; it is now evident that to proceed further will need modification of the model and/or improvement in measurement procedure.
Examination of the properties which appear to be most informative, and an attempt to segregate the operational meaning of these measurements, suggest that careful use of redundancy may lead to improvements in the channel capacity and increase the signal to noise ratio. This in turn leads to reduction of the theoretical concepts to operationally identifiable components and a clarification of the relationships between the properties and the components.
