“…Some departures from this type of depositional profile can be seen in the Lower Cretaceous platforms of the Pyrenees (Gómez‐Pérez et al ., 1998, 1999). An intriguing feature of these rudist–coral–algal‐dominated systems, shared with a number of Lower Cretaceous platforms, is the high content of muddy matrix even in zones where friction of waves and currents supposedly intersected the sea floor.…”

“…The possible influence of fleshy algae, microbial mats, microbe baffles, binders and micrite producers, or even automicrite production by biodegradation of heterotrophic micro‐organisms and calcification is probably worth considering (Gómez‐Pérez et al ., 1998; Neuweiler et al ., 1999). Other departures from the basic depositional profile can be seen in the aggradational stage of the lower Albian Gorbea platform (Gómez‐Pérez et al ., 1999). In this example, an elevated margin, lacking evidence of wave‐resistant organic frames, resulted from accumulation of boulder‐sized metazoan skeletons, creating a low‐energy back‐reef area similar to the barrier‐rimmed shelves.…”

“…Additionally in this example, steep and massive fore‐reef upper‐slope beds maintained a nearly constant thickness and depositional dips up to 35°, and only at the toe of slope the dip angle decreases and the massive beds split into thinner layers and interbed marly limestone. This constant thickness and dip of the slope clinobeds was created by automicrite precipitation, a certain degree of frame‐binding and early cementation on the slope, and indicates low rates of sediment export from the platform system (Gómez‐Pérez et al ., 1999).…”

Types of carbonate platforms: a genetic approach

Many types of carbonate platforms have been described, from homoclinal ramps to rimmed shelves and a full spectrum of variations in between; the distinction between these different types can be problematic. Nevertheless, classification of carbonate platforms is not just a semantic or academic issue. For example, it is clearly important for the accurate interpretation of seismic images of facies geometry and for assessing the potential of stratigraphic traps. Even though predictive efficiency of conceptual models depends on the degree of comprehension of the genetic factors controlling depositional profiles and the distribution of facies belts, current models for classification of carbonate platforms are basically descriptive and mainly based on depositional profile, size, and attachment to or detachment from a landmass. A genetic approach considers the variability of depositional profiles among carbonate platforms as a function of the type of sediment that was produced (basically grain size), the locus of sediment production, and the hydraulic energy. Three groups of carbonate‐producing biota may be distinguished according to their dependence upon light: (1) euphotic (good light) in shallow, wave‐agitated areas; (2) oligophotic (poor light) in deeper, commonly non‐wave‐agitated areas; and (3) photo‐independent biota in all water‐depth ranges. Several platform types in wave‐dominated seas can be considered in relation to genetic factors, even when simplifying the many possible scenarios. Euphotic framework‐producing biota create rimmed shelves similar to modern reef platforms. Soft‐substrate‐dwelling biota, which produce gravel‐sized carbonate in the shallow euphotic zone, create flat‐topped open shelves. Oligophotic gravel‐producing biota, such as some larger foraminifera and red algae, generate distally steepened ramps. Mud‐dominated carbonate production, in either euphotic or oligophotic zones, generate homoclinal ramps. Carbonate production dominated by photo‐independent biota (crinoids, sponges, bryozoans, etc.) above wave base give rise to open shelves or ramps, depending upon grain size, but may produce mounds if carbonate production occurs below the base of wave/current sweeping.

Euskokantauriar arroaren eboluzioak oso iraupen luzea du. Goi Permiarrean hasi zen, eta azken prozesuak, Miozenoan gertatu ziren. 250 Ma inguru horietan zehar, aldaketa nabarmenak izan dira bai erregimen tektoniko nagusian (luzapena, konpresioa), bai plaken arteko muga aktiboarekiko distantzian (rifta, ertz pasiboa, ertz aktiboa), eta bai azpiko lurrazalaren izaeran (kontinentala eta hipermehetua). Euskokantauriar arroak, oro har, eboluzio-prozesu konplexua du, baldintza tektoniko nagusiei egokituz pixkanaka aldatu zena.

Triassic mid‐oceanic sedimentation in Panthalassa Ocean: Sambosan accretionary complex, Japan

The Sambosan accretionary complex of southwest Japan was formed during the uppermost Jurassic to lowermost Cretaceous and consists of basaltic rocks, carbonates and siliceous rocks. The Sambosan oceanic rocks were grouped into four stratigraphic successions: (i) Middle Upper Triassic basaltic rock; (ii) Upper Triassic shallow‐water limestone; (iii) limestone breccia; and (iv) Middle Middle Triassic to lower Upper Jurassic siliceous rock successions. The basaltic rocks have a geochemical affinity with oceanic island basalt of a normal hotspot origin. The shallow‐water limestone, limestone breccia, and siliceous rock successions are interpreted to be sediments on the seamount‐top, upper seamount‐flank and surrounding ocean floor, respectively. Deposition of the radiolarian chert of the siliceous rock succession took place on the ocean floor in Late Anisian and continued until Middle Jurassic. Oceanic island basalt was erupted to form a seamount by an intraplate volcanism in Late Carnian. Late Triassic shallow‐water carbonate sedimentation occurred at the top of this seamount. Accumulation of the radiolarian chert was temporally replaced by Late Carnian to Early Norian deep‐water pelagic carbonate sedimentation. Biotic association and lithologic properties of the pelagic carbonates suggest that an enormous production and accumulation of calcareous planktonic biotas occurred in an open‐ocean realm of the Panthalassa Ocean in Late Carnian through Early Norian. Upper Norian ribbon chert of the siliceous rock succession contains thin beds of limestone breccia displaced from the shallow‐water buildup resting upon the seamount. The shallow‐water limestone and siliceous rock successions are nearly coeval with one another and are laterally linked by displaced carbonates in the siliceous rock succession.
