A carbonate platform is a sedimentary body which possesses topographic relief, and is composed of autochthonous calcareous deposits (Wilson, 1975). Platform growth is mediated by sessile organisms whose skeletons build up the reef or by organisms (usually microbes) which induce carbonate precipitation through their metabolism. Therefore, carbonate platforms can not grow up everywhere: they are not present in places where limiting factors to the life of reef-building organisms exist. Such limiting factors are, among others: light, watertemperature, transparency and pH-Value. For example, carbonate sedimentation along the AtlanticSouth American coasts takes place everywhere but at the mouth of the Amazon River, because of the intense turbidity of the water there (Carannante et al., 1988). Spectacular examples of present-day carbonate platforms are the Bahama Banks under which the platform is roughly 8km thick, the Yucatan Peninsula which is up to 2km thick, the Florida platform, the platform on which the Great Barrier Reef is growing, and the Maldiveatolls. All these carbonate platforms and their associated reefs are confined to tropical latitudes. Today’s reefs are built mainly by scleractinian corals, but in the distant past other organisms, like archaeocyatha (during the Cambrian) or extinct cnidaria (tabulata and rugosa) were important reef builders.

Forces Shaping the Incredible Steep Slopes of Carbonate Platforms
The ability to build very steep slopes is a characteristics of carbonate platforms. Microbially mediated fusing of grains and subsequent prismatic early cementation construct the margins of these edifices that are often obstacles for ocean currents along continental margins. Rock fall, margin collapse, slope canyons and slope failures are common features of carbonate slopes but cascading density currents as well as bottom and surface currents also shape the sediment distribution on the slope and in the adjacent basin. Depositional slope models largely ignore the current-related deposition. The talk will illustrate the extreme height of carbonate escarpments and the related processes using the carbonate platforms in the Florida Bahamas region.

A Redox-Based Model for Carbonate Platform Drowning and Ocean Anoxic Events
Speaker: Dr. Ben Smith, Postdoctoral Scholar, Caltech University
The deposition of marine carbonate rocks is influenced by climate and seawater chemistry. Carbonate platforms usually keep pace with subsidence and sea level, but ’platform drowning’ occurs when carbonate sedimentation slows or when siliciclastics replace carbonates. Identifying specific mechanism(s) behind platform drowning is critical for understanding global environmental changes such as Ocean Anoxic Events (OAES). We developed a model for OAEs which couples ocean basin redox processes to rates of carbonate sedimentation. Through anaerobic metabolisms, deep-ocean anoxia reduces adjusts the oceans’ delicate balance between carbonate precipitation and dissolution. This quasi-steady state response acts over long timescales ...
