“…This is a classical locality for the "Orbitolina level" of southern Apennines (De Castro, 1963;Cherchi et al, 1978). The lower half of the section (from 0 to 24 m) is exposed in an abandoned quarry (40 • 42.01" N, 14 • 51 43" E) and has been the object of many papers dealing mainly with cyclostratigraphy (Raspini, 1998(Raspini, , 2011D'Argenio et al, 1999b. The section continues on the mountain slope above the edge of the quarry.…”

Abstract. Low biostratigraphic resolution and lack of chronostratigraphic calibration hinder precise correlations between platform carbonates and coeval deep-water successions. These are the main obstacle when studying the record of Mesozoic oceanic anoxic events in carbonate platforms. In this paper carbon and strontium isotope stratigraphy are used to produce the first chronostratigraphic calibration of the Barremian-Aptian biostratigraphy of the Apenninic carbonate platform of southern Italy. According to this calibration, the segment of decreasing δ 13 C values, leading to the negative peak that is generally taken as the onset of the Selli event, starts a few metres above the last occurrence of Palorbitolina lenticularis and Voloshinoides murgensis. The following rise of δ 13 C values, corresponding to the interval of enhanced accumulation of organic matter in deep-water sections, ends just below the first acme of Salpingoporella dinarica, which roughly corresponds to the segment of peak δ 13 C values. The whole carbon isotope excursion associated with the oceanic anoxic event 1a is bracketed in the Apenninic carbonate platform between the last occurrence of Voloshinoides murgensis and the "Orbitolina level", characterized by the association of Mesorbitolina parva and Mesorbitolina texana. Since these bioevents have been widely recognized beyond the Apenninic platform, the calibration presented in this paper can be used to pinpoint the interval corresponding to the Early Aptian oceanic anoxic event in other carbonate platforms of central and southern Tethys. This calibration will be particularly useful to interpret the record of the Selli event in carbonate platform sections for which a reliable carbon isotope stratigraphy is not available.

“…This culminates with the Sequence Boundary Zone (SBZ1) above the "Orbitolina Level", as testified by the maximum abundance of characean-rich sediments. According to D'Argenio et al (1999), these ∼8 m-thick deposits represent about 800 ka. The same result was also obtained from a study Lucia et al (2011), it would imply that: (i) taking into account the duration of the Selli Level (e.g.…”

“…This is possible if the vertical evolution of the lithofacies and the variation in thickness of the different orders of cycles in a section are considered to be the result of the response of interior depositional settings to variations of accommodation space which determined the typical geometry of the systems tracts in corresponding seaward deposits (e.g. Montañez and Osleger, 1993;Kerans, 1995;D'Argenio et al, 1999;Sandulli and Raspini, 2004). Along the Tobenna-Faito composite section, lithofacies trends within the superbundles frequently reflect transgressions and regressions.…”

“…In order to clarify the palaeoenvironment of the "Orbitolina Level", the microbial carbonates and the Salpingoporella dinarica-rich sediments in the lagoonal setting of the Aptian-Albian Apenninic carbonate platform, previous sedimentological, cyclostratigraphic and chemostratigraphic studies (Raspini, 1996(Raspini, , 1998D'Argenio et al, 1999;Raspini, 2001;D'Argenio et al, 2004) are synthesized, integrated and upgraded on the basis of further field and laboratory work. These peculiar facies of the Tobenna-Faito composite section are described and interpreted in relation to long-term changes in accommodation space on the shelf as well as to volcanic, oceanographic and climatic events during the Aptian.…”

Abstract. This paper discusses the palaeoenvironmental significance of the "Orbitolina Level", the microbial carbonates and the Salpingoporella dinarica-rich deposits encased in the Aptian/Albian shallow water carbonate platform strata of Monte Tobenna and Monte Faito (Southern Italy). These facies show a peculiar field appearance due to their color and/or fossil content. In the shallow water carbonate strata, the Late Aptian "Orbitolina Level" was formed during a period of decreasing accommodation space. Microbial carbonates occur in different levels in the composite section. They reach their maximum thickness around the sequence boundaries just above the "Orbitolina Level" and close to the AptianAlbian transition, and were not deposited during maximum flooding. S. dinarica-rich deposits occur in the lower part of the Monte Tobenna-Monte Faito composite section, in both restricted and more open lagoonal sediments. S. dinarica has its maximum abundance below the "Orbitolina Level" and disappears 11 m above this layer.On the basis of δ 13 C and δ 18 O values recorded at TobennaFaito, the succession has been correlated to global sea-level changes and to the main volcanic and climatic events during the Aptian. Deterioration of the inner lagoon environmental conditions was related to high trophic levels triggered by volcano-tectonic activity. Microbial carbonates were deposited especially in periods of third-order sea level lowering. In such a scenario, periods of increased precipitation during the Gargasian induced the mobilization of clay during flooding of the exposed platform due to high-frequency sea-level changes, with consequent terrigenous input to the lagoon. This and the high nutrient levels made the conditions unsuitable for the principle carbonate producers, and an opportunistic biota rich in orbitolinids (Mesorbitolina texana and M. parva) populated the platform. In the more open marine domain, the increased nutrient input enhanced the production of organic matter and locally led to the formation of black shales (e.g. the Niveau Fallot in the Vocontian Basin).It is argued that the concomitant low Mg/Ca molar ratio and high concentration of calcium in seawater could have favoured the development of the low-Mg calcite skeleton of the S. dinarica green algae.During third-order sea-level rise, no or minor microbial carbonates formed in the shallowlagoonal settings and S. dinarica disappeared. Carbonate neritic ecosystems were not influenced by the environmental changes inferred to have been induced by the mid-Cretaceous volcanism.The "Orbitolina Level", the microbial carbonates and the Salpingoporella dinarica-rich deposits in the studied Aptian/Albian shallow water carbonate strata are interpreted to be the response to environmental and oceanographic changes in shallow-water and deeper-marine ecosystems.
