To evaluate controls on small-scale sequences (up to tens of m) deposited during ice-house periods that maintain similar thickness throughout wide geographic areas despite draping topography and containing facies that both build and fill relief.
Expect build-and-fill sequences to develop during periods of high frequency-high amplitude sea-level fluctuations when carbonate production is not optimal.
Build-and-fill sequences form in the build-and-fill zone, in middle ramp/shelf settings that lie between highstand and lowstand positions.
Build-and-fill sequence architecture may be predictable given knowledge of the sea-level history, paleotopography, and controls on sediment production and dispersal.
Many shallow-water carbonate facies fill low areas as opposed to building relief on paleohighs.
Siliciclastics can fill or build relief.
The alternation of building and filling processes during a single sea-level cycle produces a thin widespread sequence with complex internal architecture.
