“…According to Bosence et al (2009), these cycles can be generated only by allocyclic controls. The common character of these cycles is the scarcity of intertidal facies, dominance of subtidal facies Bosence et al 2009), although the formation displays a remarkable thickness of up to 700 m (Pialli 1971;Colacicchi et al 1975;Bigozzi 1990;Barattolo & Bigozzi 1996;Passeri & Venturi 2005;Bosence et al 2009). In this work, we present a high-resolution analysis of a very well exposed road cutting (26 m exposed thickness) located in the structural high of the Cornicolani Mountains at the end of the upper portion of the Calcare Massiccio Formation, around 40 m before the drowning succession.…”

“…The articulated physiography was attributed to the beginning of tectonic extension, which created two different domains: a persistent carbonate platform (Latium-Abruzzi domain) and a deep-water domain (Umbria-Sabina Basin) with intrabasinal structural highs. On the structural highs, the Calcare Massiccio Formation is characterized by peritidal cyclical sedimentation and is usually overlain by pelagic sea-mount deposits represented by condensed pelagic cephalopod-rich carbonates of the upper Pliensbachian-Tithonian Bugarone unit (reduced sequences) that are no more than a few tens of metres thick (Centamore et al 1971;Pialli 1971;Colacicchi et al 1975). Deposition in the structural depressions was characterized by the relatively deep, subtidal Calcare Massiccio Formation that does not show evidence for cyclical sedimentation (Santantonio 1993).…”

This paper shows the environmental changes and high-frequency cyclicity recorded by Lower Jurassic shallow-water carbonates known as the Calcare Massiccio Formation which crop out in the central Apennines of Italy. Three types of sedimentary cycle bounded by subaerial erosion have been recognized: Type I consists of a shallowing upward cycle with oncoidal floatstones to rudstones passing gradationally up into peloidal packstone alternating with cryptoalgal laminites and often bounded by desiccation cracks and pisolitic-peloidal wackestones indicating a period of subaerial exposure. Type II shows a symmetrical trend in terms of facies arrangement with peloidal packstones and cryptoalgal laminites present both at the base and in the upper portion of the cycle, separated by oncoidal floatstones to rudstones. Type III displays a shallowing upward trend with an initial erosion surface overlain by oncoidal floatstones to rudstones that, in turn, are capped by pisolitic-peloidal wackestones and desiccation sheet cracks. Sheet cracks at the top of cycles formed during the initial phase of subaerial exposure were successively enlarged by dissolution during prolonged subaerial exposure. The following sea-level fall produced dissolution cavities in subtidal facies, while the successive sea-level rise resulted in the precipitation of marine cements in dissolution cavities. Spectral analysis revealed six peaks, five of which are consistent with orbital cycles. While a tectonic control cannot be disregarded, the main signal recorded by the sedimentary succession points toward a main control related to orbital forcing. High frequency sea-level fluctuations also controlled diagenetic processes.

“…Fifteen lithofacies have been identified in the 16 studied sections and have been defined by lithology, sediment constituents and sedimentary structures (Table 1). Many of these facies are very well‐known and several studies have described and interpreted very similar facies from the Early Jurassic of Tethys (Colacicchi et al. , 1975; Crevello, 1991; Rey, 1997; Bosence et al.…”

Facies architecture and cyclicity in a mosaic carbonate platform: effects of fault‐block tectonics (Lower Lias, Causses platform, south‐east France)

International audienceIn the Causses platform (south-east France), Late Hettangian to Sinemurian deposits were interpreted previously as shallow-water carbonate ramp deposits. A new look at these deposits has shown a fault-controlled mosaic carbonate platform that is different from the carbonate ramp models. Within the platform mosaic, 15 lithofacies have been recognized, which are organized in four facies associations, including peritidal, restricted shallow sub-tidal, sand dunes and sub-tidal shelf facies associations. The rapid lateral and vertical facies changes, and the lack of consistent landward or seaward direction indicated by the pattern of facies changes, question the existence of a shoreline suggested by the traditional models for this region. Instead, the facies organization and cycle stacking pattern suggest deposition in a mosaic of intertidal islands between which sub-tidal restricted or open conditions could coexist in very close proximity. Such a platform mosaic would have been defined by tectonic activities along normal faults which segmented the shallow-water Causses platform. The facies and facies associations are arranged into metre-scale, peritidal and sub-tidal cycles that are also variable. Certain cycles show the same stacking pattern in all the sections and seem to be traceable over tens of kilometres. On the contrary, other cycles cannot be correlated; they are present only in specific sections and have a maximum lateral extension of 1 or 2 km. These metre-scale cycles stack to form four medium-scale cycles bounded by surfaces that display sub-aerial exposure features. Medium-scale cycles stack into two larger-scale cycles (tens of metres thick) and are bounded by well-defined karstic surfaces. Based on their lateral continuity and their stacking pattern, the metre-scale cycles are controlled probably by high frequency eustatic variations overprinting the topographic irregularities formed by differential subsidence of fault-bounded blocks. Episodic fault activities may reorganize the topography so that, even if eustatic changes may still be the major control of cycles, the expression and number of cycles could be different. Cycles of medium and large-scale are interpreted as being allogenic, controlled by changes in eustasy and/or subsidence rates as evidenced by their lateral continuity and the correlations of the large-scale cycles with third-order depositional sequences

Existing facies models for peritidal carbonates are limited in number and do not reflect the wide spe.ctrum of possible types The major depositional processes in peritidal carbonate environments are reviewed in order to stress the complex nature of the systems. The tidal channel model is critically discussed and it is suggested that channel deposits may be of minor importance in typical shoaling-up sequences. The possible causes of multiple asymmetrical sequences are reviewed.
