Guides géologiques - Bourgogne : Côte-d'Or et Saône-et-Loire.

2016

256 pages; National audience; Ce guide propose surtout 10 itinéraires pédestres géologiques à travers les paysages remarquables de la région de le Bourgogne Sud représentée par deux de ses départements : la Côte-d'Or et la Saône-et-Loire. Ce territoire bourguignon est riche géologiquement et se caractérise par la diversité des roches que l'on peut y observer. Depuis les granites jusqu'aux roches sédimentaires, en passant par les roches métamorphiques et volcaniques ; elles s'y trouvent pratiquement toutes. Cette région a aussi subi les phases glaciaires qui vont creuser, dans la couverture sédimentaire calcaire de la Bourgogne, les nombreuses combes, petites vallées qui entaillent les colli…

Reconstitution des environnements de dépôtdu Carbonifère supérieur/ Permien inférieurau Sud du bassin de Paris : implicationgéodynamique

2016

National audience; La période Carbonifère-Permien marque un changement drastiquede régime tectonique (fin de l’Orogenèse hercynienne -début d’une phase de rifting). Cette transition s’enregistre dansles bassins sédimentaires contemporains. En Europe de l’Ouest,ces bassins, principalement constitués de sédiments continentauxet de séries volcano-sédimentaires (largement sous-estimées),sont mal contraints sur beaucoup d’aspects (sédimentaire, tectonique,volcanique et corrélations spatio-temporelles). Le cadrechronologique de ces bassins est également mal connu dans lamesure où les principaux âges ont été estimés par palynologie àpartir de faciès floristiques ayant pu coexister dans le temps.Un…

Early Jurassic normal faulting in a carbonate extensional basin: characterization of tectonically driven platform drowning (High Atlas rift, Morocco).

2009

18 pages; International audience; This paper describes a tectonostratigraphic model of the synrift evolution of the Early Jurassic High Atlas rift of Morocco. The model is constrained by mapping of a set of inverted extensional blocks, by facies analysis of carbonate platform and turbiditic to hemipelagic synrift deposits, and by high-resolution (n 3 100 ka) biostratigraphy of the Early Jurassic succession. The chronostratigraphic packages of the High Atlas of Rich vary significantly in thickness, facies and architecture from one tectonic block to another. Our study shows how synrift strain varied in space and time over a long time interval (14 Ma) around the High Atlas rift. Initially, in …

Deep basin record evolution of chemical weathering and physical erosion as response to the tectonic uplift of the South African Plateau during the up…

2022

<p>During the upper Cretaceous the South African Plateau underwent an uneven uplift period that coincided with the onset of a long-term climate cooling. This uplift recorded two pulses, an early pulse during the Turonian that affected the eastern margin and a later pulse occurred during the Campanian affecting the western margin (van der Beek et al., 2002; Braun et al., 2014; Baby et al., 2020). We aim here to determine the response of physical erosion and chemical weathering to this tectonic event, that may have played a role in the long-term climate cooling by promoting silicate weathering and associated atmospheric CO<sub>2</sub> drawdown. In thi…
