Hiatal surfaces in carbonate strata are ubiquitous, based on long-term accumulation rates that are orders of
magnitude slower than instantaneous rates of sediment production and
accumulation. Ten years ago, Burgess and Wright used a numerical model of peritidal carbonate systems to
explore the lateral extent, thickness, and completeness of facies. The results of these experiments reveal how
variable processes of production, transport, erosion, and accumulation create
complex facies patterns, although complexity can be modified by feedbacks
within the depositional system. Burgess and
Wright concluded that preserved strata represent punctuated deposition, driven
by interactions between stochastic and deterministic processes, and thus the
stratigraphic record is more complex than suggested by conventional sequence
stratigraphic models.
