Ce projet traite de récifs coralliens récemment découverts au sud de la China. Cette découverte est en contradiction avec la thèse établie que suite à la crise majeure du Dévonien terminal, les récifs coralliens seraient absents durant le Carbonifère. Les analyses envisagées comprennent une cartographie des lithofaciès, la pétrographie, biostratigraphie, paléoécologie, chimiostratigraphie. Une reconstruction des plateformes carbonatées du sud de la Chine est envisagée.
Lay summary

Ce projet traite de récifs coralliens récemment découverts au sud de la China. Cette découverte est en contradiction avec la thèse établie que suite à la crise majeure du Dévonien terminal, les récifs coralliens seraient absents durant le Carbonifère. Les analyses envisagées  comprennent une cartographie des lithofaciès, la pétrographie, biostratigraphie, paléoécologie, chimiostratigraphie. Une reconstruction des plateformes carbonatées du sud de la Chine est envisagée.
L’objectif principal est de proposer un scénario susceptible d’expliquer la présence des récifs coralliens. L’étude permettra de tester  l’hypothèse que l’apport terrigène lié à l’Orogenèse serait inhibiteur du développement de récifs coralliens dans les zones limitrophes des centres d’orogenèse de l’ouest de la Paléo-Téthys, contrairement aux zones lointaines telles que le sud de la Chine. Ce scénario aurait des implications sur notre compréhension de l’évolution des systèmes récifaux et de leur vulnérabilité aux changements globaux.

Abstract

This project deals with extended coral reefs discovered recently in Guizhou and Langping, south China. This discovery is at odd with current published data that the Mississippian-Pennsylvanian (“Carboniferous”) is a “reefless lag time”, following the Frasnian-Famennian extinction event. Research plan encompasses lithofacies mapping, petrography/microfacies analysis, biostratigraphy, paleoecology, chemiostratigraphy, and platform reconstruction. The goal is to reconstruct the overall depositional setting and suggest a robust scenario to explain the occurrence of extended Carboniferous coral reefs in South China. Investigation will allow testing the hypothesis that the continental runoff resulting from Orogens inhibited the development of metazoan reefs in the western Paleo-Tethys whereas setting remote from the runoff developed extended metazoan reefs (South China and settings such as Japan and Thailand) after the Frasnian-Famennian extinction event.Coral reefs in China fill, and significantly shorten, the duration the end-Devonian reef gap. Results will lead to reconsider reef evolution globally, and the potential of coral reef to persist in specific settings during intervals of harsh perturbations. This has a significant scientific and societal impact in the context of current and predicted future global perturbations.
