“…These factors are consistent with a global highstand in sea level (Bond et al, 1989Haq and Schutter, 2008) and the flooding of huge cratonic areas. Consequently, extensive epeiric seas with carbonate and mixed siliciclastic-carbonate deposition developed.…”

“…42B; Keller, 1995). On both margins of Laurentia, the onset of carbonate platform deposition is broadly correlative with the Bonnia-Olenellus trilobite zone (Bond et al, 1989). Similarly, the oldest carbonates in the Precordillera belong to the Bonnia-Olenellus zone.…”

The Argentine Precordillera ("Precordillera") is part of a larger terrane which is exotic to the western margin of Gondwana. This larger terrane is characterized by a Grenvillian-type basement and the presence of Laurentian carbonate-platform rocks of Cambrian-Ordovician age. The original position of the terrane is interpreted to be the Ouachita embayment of southeastern Laurentia.Terminal Neoproterozoic continental breakup and the formation of the Appalachian-Ouachita margin during the late Precambrian-Early Cambrian established a passive margin to the present east of the Precordillera. This passive margin is the original continental margin of Laurentia, which was located outboard of the Precordillera. Continuous crustal extension during the Cambrian along the Ouachita margin created a marginal plateau that accommodated the Argentine Precordillera carbonate platform. This marginal plateau to Laurentia was separated from mainland Laurentia by a deep graben system, today represented by the offshore Ouachita facies of the southeastern United States. The Cambrian through earliest Middle Ordovician mark the climax of the Laurentian episode because the Argentine Precordillera sediments and fauna are indistinguishible from Laurentia.In the carbonate platform succession of the Argentine Precordillera, the La Laja Formation marks the transition from rift-related redbeds to carbonate sedimentation. The La Laja Formation was deposited on a platform seaward of the nearshore siliciclastic trap but inboard of a (only partly exposed) carbonate belt which might have marked the platform margin. Several third-order cycles developed; differential rates of sea-level rise were the driving forces for cycle formation. Near the base of the La Laja Formation, a sandy interval is separated from the older rocks by a presumed hiatus. This hiatus might represent the Hawke Bay regression event of the eastern margin of Laurentia. Upper Cambrian limestones and dolostones of the Zonda and La Flecha Formations record the evolution of vast peritidal flats. The spatial and biostratigraphical relations between both formations are not clear and await further research. At present, it seems that the lower, more calcareous facies of the La Flecha Formation in the Guandacol subbasin is coeval to the dolomite facies of the Zonda Formation in the San Juan subbasin. The last important terrigenous input is noticed inMarjuman sediments of the La Flecha Formation, which marks a major shift in coastal onlap toward the hinterland. The Tremadocian La Silla Formation reflects a somewhat deeper environment, although open-marine rocks are absent. However, extensive tidal flats are also absent. The rocks are mud-dominated limestones and dolostones with locally abundant oolites. 1 Geological Society of America Special Paper 341 1999 on July 16, 2015 specialpapers.gsapubs.org Downloaded from Small-scale cycles are locally present. The general arrangement of facies is best explained by a tidal-flat island model. The La Silla Formation shows the most uniform facies deve...

“…Most of the platforms, however, show growth rates in the order of 100 to 150 Bubnoff Units. Figure 4 exhibits a kind of rhythmicity Bond et al 1989Appalachians, USA 48.7 Read 1989 in that way that periods with growth rates of 100 to 150 Bubnoff Units alternate with longer periods of around 50 Bubnoff Units and even less. These periods of lower reef growth rates may also include more "deep-water" type reefs than others and therefore impacting on the growth rate pattern of through Earth history.…”

The growth potential of modern zooxanthellate corals from the major reef provinces is reviewed with respect to Holocene reef growth. Both coral growth and reef growth is enhanced globally at the beginning of the Holocene and is maintained regionally in the Caribbean Sea up to the present in contrast to reefs of the Indo-Pacific Ocean. This regional difference is mainly caused by the siphoning effect of the tropical Atlantic, which is characterised still by a rising sea level in contrast to global ocean. Hence, Indo-Pacific reefs exhibit a well-cemented reef crest and reef roof barren of living corals. The evaluation of reef growth rates throughout the Phanerozoic shows reduced growth rates of more than one order of magnitude in comparison to their modern counterparts. This is a result of compaction and diagenesis but also strongly biased by uncertainties in absolute dating. Point counting of individual framebuilders with known growth rate may result in more comparative figures for growth rates of fossil reefs with respect to modern ones.
