Physical analogs to the statistical properties of a theoretical flicker noise model are extracted from published accounts of the character of the record. Analogies are drawn between the temporal scales of variability of sedimentary processes, and the spatial scales of acoustic impedance variability. A linear model is proposed as a first approximation. It is consistent with both impedance characteristics and the dual, cyclic spatial and episodic temporal, nature of the sedimentary record. This model consists of the superposition of independent random processes having logarithmically distributed correlation times. Processes occurring over some discrete frequency range define distinct scales of 'stability' in the evolution of sedimentary environments. The contribution which a range of frequencies makes towards the character of the impedance spectra is a reflection of the continuity of conditions favouring the deposition of a particular lithology. The magnitude of change at a particular scale is a reflection of the recurrence interval of effective processes.
