  • The Apulia Carbonate Platform—Gargano Promontory, Italy (Upper Jurassic–Eocene)
    AAPG Bulletin, 2017
    Co-Authors: Michele Morsilli, Alex Hairabian, Jean Borgomano, Sergio Nardon, Erwin W. Adams, Guido Bracco Gartner
    Abstract:

    The Upper Jurassic to Eocene Carbonate rocks of the Gargano Promontory belong to the Apulia Carbonate Platform (ACP) and provide a spectacular and complete succession of slope and base-of-slope resedimented gravity flow Carbonates with preserved reservoir properties and, with its coeval Carbonate Platform, displaying various tectonostratigraphic architectures. The ACP margin is characterized by an overall aggrading architecture, and different geometric and depositional features. Facies types and sedimentary dynamics of the Carbonate slope and gravity deposits can be analyzed with respect to the stratigraphic architecture of the Platform-to-basin transition. These outcrops are the only analogs of some important oil reservoirs and plays present in the equivalent slope to basin succession in the Adriatic offshore and elsewhere.

  • Carbonate Platform evidence of ocean acidification at the onset of the early toarcian oceanic anoxic event
    Earth and Planetary Science Letters, 2012
    Co-Authors: Alberto Trecalli, Jorge Enrique Spangenberg, Karl B. Föllmi, Thierry Adatte, Mariano Parente
    Abstract:

    Abstract The early Toarcian oceanic anoxic event (Early Jurassic;∼183 Myr ago) is associated with one of the largest negative carbon isotope excursion (CIE) in the whole Phanerozoic (3–7‰). Estimates of the magnitude and rate of CO 2 injection in the ocean–atmosphere system are compatible with a scenario of ocean acidification. Many Carbonate Platforms drowned in the Pliensbachian, well before the early Toarcian event. In this paper we test the hypothesis of surface water ocean acidification by presenting data from a resilient Carbonate Platform: the Apennine Carbonate Platform of southern Italy. The studied sections document a dramatic shift of the Carbonate factory from massive biocalcification to chemical precipitation. Lithiotis bivalves and calcareous algae ( Palaeodasycladus mediterraneus ), which were the most prolific Carbonate producers of Pliensbachian Carbonate Platforms, disappear during the first phase of the early Toarcian CIE, before the most depleted values are reached. We discuss the local versus supraregional significance of this shift and propose a scenario involving abrupt decline of Carbonate saturation, forced by CO 2 release at the beginning of the early Toarcian CIE, followed by a calcification overshoot, driven by the recovery of ocean alkalinity. Attribution of the demise of Carbonate Platform hypercalcifiers to ocean acidification is supported by palaeophysiology and reinforced by experimental data on the detrimental effects of ocean acidification on recent shellfishes and calcareous algae.

  • bio chemostratigraphy of the barremian aptian shallow water Carbonates of the southern apennines italy pinpointing the oae1a in a tethyan Carbonate Platform
    Solid Earth, 2011
    Co-Authors: M Di Lucia, Alberto Trecalli, Maria Mutti, Mariano Parente
    Abstract:

    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 δ13C 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 δ13C 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 δ13C 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.

  • Carbonate Platform production during the Cretaceous.
    Geological Society of America Bulletin, 2020
    Co-Authors: Alexandre Pohl, Alex Hairabian, Yannick Donnadieu, Yves Godderis, Cyprien Lanteaume, Camille Frau, Julien Michel, Marie Laugie, John J.g. Reijmer, Christopher R. Scotese
    Abstract:

    Platform Carbonates are among the most voluminous of Cretaceous deposits. The production of Carbonate Platforms fluctuated through time. Yet, the reasons for these fluctuations are not well understood, and the underlying mechanisms remain largely unconstrained. Here we document the long-term trend in Cretaceous Carbonate Platform preservation based on a new data compilation and use a climate-carbon cycle model to explore the drivers of Carbonate Platform production during the Cretaceous. We show that neritic Carbonate preservation rates followed a unimodal pattern during the Cretaceous and reached maximum values during the mid-Cretaceous (Albian, 110 Ma). Coupled climate-carbon cycle modeling reveals that this maximum in Carbonate deposition results from a unique combination of high volcanic degassing rates and widespread shallow-marine environments that served as a substrate for neritic Carbonate deposition. Our experiments demonstrate that the unimodal pattern in neritic Carbonate accumulation agrees well with most of the volcanic degassing scenarios for the Cretaceous. Our results suggest that the first-order temporal evolution of neritic Carbonate production during the Cretaceous reflects changes in continental configuration and volcanic degassing. Geodynamics, by modulating accommodation space, and turnovers in the dominant biota probably played a role as well, but it is not necessary to account for the latter processes to explain the first-order trend in Cretaceous neritic Carbonate accumulation in our simulations.

  • Characterization of the Devonian Kharyaga Carbonate Platform (Russia): Integrated and multiscale approach
    AAPG Bulletin, 2015
    Co-Authors: Vincenzo Spina, Jean Borgomano, Georges Nely, Natalia Shchukina, Alan Irving, Catherine Neumann, Valerie Neillo
    Abstract:

    ABSTRACT The Devonian Carbonate Platform (Obj-2) of the Kharyaga field (Russia) has been operated by Total since 1999 and produces 42° API oil, rich in H2S. A multidisciplinary (sedimentological, structural, stratigraphic, and geomechanical modeling) and multiscale study was made of the field, integrating seismic, micro-resistivity log, and core data to characterize the reservoir. The Kharyaga Carbonate Platform is characterized by complex relationships among sea-level variations, subsidence, and sedimentation rates. The field is divided into a Platform edge (barrier zone) in the southern area, and back barrier and lagoon environments to the north, each characterized by different facies distribution and dynamic behavior. The Platform shelf and the reef flat show dome-shaped thrombolites; the back barrier is characterized by grainstone shoals associated with columnar stromatolites, whereas the lagoon comprises peloidal wackestones and packstones associated with laminated fenestral stromatolites. Significant and prolonged subsidence, in both the lagoon and the Platform edge, is associated with partial emergence of the Platform reef, as shown by karst development. Seismic interpretation highlighted both underlying north-south structures and syndepositional east-west collapse faults along the southern barrier edge. Two-dimensional and three-dimensional sedimentological modeling of the Obj-2, calibrated by well data and core analyses, allowed the simulation of alternative scenarios to explain the evolution of the Carbonate Platform during the Devonian and suggested the observed facies distribution is compatible with the presence of a fixed outer Platform edge represented by east-west faults. The Carbonate Platform of the Kharyaga field exhibits complex behavior; hydrocarbon (HC) accumulation and flow is controlled by the interplay of primary porosity, karst distribution, and structural discontinuities (faults and fractures). Besides the role of the karstification, this paper mainly focuses on the role played by tectonic structures on the evolution of the Carbonate Platform and on the HC flow. From drill stem test data, east-west faults and karsts are considered as major permeability heterogeneities, but interference tests showed more complex fluid pathways at the smaller scale. Microresistivity images show dominant northeast-southwest and northwest-southeast fracture sets in the central barrier, forming an interconnected flow network with the seismic faults. Geomechanical modeling suggests that these fractures are subseismic structures linked to inherited, deep-seated faults active at the time of fracturing, in addition to the listric reservoir faults.
