Microbial carbonates and high-relief carbonate platforms

Giovanna Della Porta - University of Milan

Microbial carbonates dominated in the Phanerozoic during times of skeletal biota crises and environmental perturbations. High-relief platforms with steep slopes and margins with microbial boundstone reefs are non actualistic examples of highly productive carbonate systems largely representative of the late Palaeozoic, Triassic and Jurassic depositional record. This review explores the controls on facies character, depositional geometry and architecture of several examples of high-relief carbonate platforms evaluating the responses of the microbial carbonate factory, stratal geometry and platform growth to changes in accommodation.
