SUMMARY

The quantitative relationships between stratigraphical variables from a succession of coal-bearing cycles deposited in a subsiding basin have been investigated using principal component- and factor analysis, in an attempt to reveal simple relationships undetected by conventional qualitative methods. Knowledge of such relationships will undoubtedly be useful in future computer simulation studies of cyclical sedimentation. Principal component analysis and factor analysis yield similar results, which confirm and amplify those of the trend surface analysis described in Read and Dean (1967).
