A unique aspect
of carbonate platforms is their ability to develop flanks with gradients that
exceed the angle of repose due to early cementation and binding. Frost et al. document a Permian
example of an oversteepened carbonate platform margin that was impacted by
early syndepositional deformation.
A suite of field, petrographic, and stable isotopic data reveal that
these early fractures and faults also facilitated the flow of early
dolomitizing fluids. These results
are interpreted to reveal a spatially and temporally complex alteration of host
limestone that led to bed-scale heterogeneity in dolomite patterns and
petrophysical properties.
