“…The change from carbonate-dominated to siliciclastic-dominated sedimentation during the mid-Asbian must be explained in other terms. James and Mountjoy (1983) showed that sediment starvation of a basin could be achieved if carbonate production on surrounding platforms was shut down by drowning or emergence. There is no evidence of regional drowning of the Derbyshire carbonate platform during mid-Asbian times which could account for this change in sedimentation.…”

The Dinantian Edale Basin is located to the north of the Derbyshire carbonate platform and underlies the Upper Carboniferous of the central Pennines. The Edale Basin was thought to be part of a large basin which extended from the Derbyshire carbonate platform to the Askrigg Block. The presence of aggregate grains and ooids in the Alport Borehole suggests that a carbonate platform, possibly located on the Holme structural high, was present underneath the central Pennines. This platform is called the Holme Platform.The Arundian to early Asbian section of the Alport Borehole represents deposition of resedimented shallow-water carbonates with occasional bioturbated periplatform carbonates and basinal shales on the middle part of a carbonate ramp. Volcaniclastic sediments may have been derived from a volcanic centre within the Edale Basin.A change in sedimentation during the mid-Asbian to the deposition of basinal shales and distal carbonate turbidites is attributed to starvation of the basin. This may have been caused by a combination of the development of accretionary rimmed carbonate shelves and the repeated emergence of shelf carbonates deposited on surrounding carbonate platforms. The late Asbianiearly Brigantian section of the Edale Borehole is interpreted as a distal equivalent of the 'Beach Beds' which outcrop at the north margin of the Derbyshire carbonate platform. The 'Beach Beds' represent bioclastic turbidites derived from the Derbyshire carbonate platform.Throughout the Brigantian, sedimentation in the Edale Basin was dominated by the deposition of distal carbonate turbidites and basinal shales. Variation of dip through the Alport Borehole indicates the common occurrence of slumps throughout the sequence and the presence of either an angular unconformity or a fault within the early Brigantian section.

“…This line source was essentially the carbonate platform, as the majority of the olistoliths are carbonates. Although the carbonate platform was essentially dead by the time the Los Sombreros Formation was deposited, it still behaved like a bypass margin (James and Mountjoy, 1983). Bypass margins of carbonate platforms are characterized by slope and platform edge failure due to oversteepening and the origination of debris flows, slides, and slumps, which are deposited at the toe of slope.…”

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...
