A mathematical modelling approach is used to investigate (i) the vertical and lateral facies variations in the coal-bearing Sydney Subgroup, and (ii) the influence of active structures on Permo-Triassic sedimentation in the southern Sydney Basin. A Markov chain model is employed in conjunction with detailed borelog data compiled by the author to explore the cyclic characteri stics of the Sydney Subgroup. The model is based substantially upon an embedded Markov model developed by Doveton, with modifications appropriate to the form of the sequence data. During the application of the model, careful consideration was given to the mathematical assumptions and to the rationale of structuring the sequences.
