Confined aquifers, generally more protected from anthropogenic pressure, present potential alternative water resources of good quality to surface and subsurface resources. However, their exploitation, potentially affecting the resource in a long-term way, requires understanding functioning ensure sustainable management. In order gain some processes involved confined we here results obtained multilayered Beauce limestone aquifer, Centre region France. This aquifer is already heavily exploited...
The objective of this study is to synthesize the geological and hydrogeological characteristics main aquifers in Paris Basin within Cenozoic sedimentary formations. This work part multi-annual scientific program RGF (Référentiel Géologique de la France, https://rgf.brgm.fr/page/bassin-parisien), which aims update representation mapping French geology on a national scale. also funds several PhD projects collaboration with academic community, focusing geometry,...
The European Cenozoic Rift Intraplate System (ECRIS) is a deep crustal discontinuity. On the surface, its longest segment, Rhine Basin, large scale asymmetric rift that has been largely studied by sedimentary and tectonic inquiries for oil geothermal potential. However, mechanism behind development still under discussion. Different scenarios co-exist, among them an East-West Oligocene extension of unknown origin (Bergerat, 1985), transtensive opening, associated with North-South compression...
The Aptian-Albian deposits of the Anglo-Paris Basin consist terrigenous sediments formed in shallow continental and coastal environments within an extensional intracratonic basin. interval is rarely exposed, except Wessex Basin, where subsiding sub-basins developed during Early Cretaceous were later exposed due to tectonic inversion (Chadwick, 1993). Outcrops southern England, Cap de la Hève (Normandy), Burgundy quarries complement subsurface data from Paris drill cores....
Abstract The difficulty of correlating continental deposits hinders predicting lacustrine and palustrine carbonate facies variations in time space. This study aims to understand better the factors governing these heterogeneities by measuring isotopes conducting facies, petrographic sequence stratigraphic analyses Lutetian–Aquitanian Paris Basin, that record transition from marine environments. Large‐scale correlations enabled definition two lacustrine–palustrine models. (1) coastal system...
Abstract. The uppermost Cretaceous to early Palaeogene is a period of major deformations the western part Eurasian plate with prominent basin inversions starting from Coniacian onwards. These occur in complex geodynamic setting within both context Africa–Eurasia convergence and North Atlantic opening. While Mesozoic graben have been extensively studied, particularly Eastern Europe Sea, more gentle that affect thicker crust areas (intracratonic basins emerged lands) are not as well...
Abstract Sediment accumulation rates in foreland basins result from a complex interplay between surface and deep processes both the exhumed relief domain sedimentary basins. The growth decay of mountain belt during orogenic post‐orogenic phases have been largely studied, thanks to thermochronological structural studies. response preserved sediments surrounding is well known terms filling patterns architecture, but much less better quantified. Here, we performed measurement siliciclastic...
The French Massif Central is a key basement relief. This region experienced an intense period of alkaline volcanism, beginning with the Cantal Stratovolcano at 11 Ma and ending 3 Ma. To quantify palaeoelevation to replace it in frame uplift history Central, we first reconstructed vegetation climate based on pollen analysis Murat diatomites, which were deposited maar lake. was organized three different belts: Glyptostrobus swamp around lake; mixed forest; and, higher altitudes, conifer...
Abstract An understanding of the evolution foreland basins improves our knowledge how mountain belts have grown and helps us to decipher events which may not be preserved in orogen. The infilling north Pyrenean retro‐foreland basin (Aquitaine Basin, France) during main exhumation Pyrenees its corresponding thermal history been fully investigated. We applied apatite fission track (AFT) (U‐Th‐Sm)/He (AHe) methods coupled with inverse modelling on both detrital Eocene (47 33 Ma) syn‐orogenic...
Abstract Dating the onset of ancient (>1 Ma) karstification is a challenge. One approach to date earliest calcite cements in speleothems. We show benefits situ U-Pb dating directly on thin sections from (ca. 30 (<1 mm) speleothems karstified Lower Oligocene lacustrine-palustrine carbonates Paris Basin (France), which cannot be dated using other methods. 32 rafts (a type speleothem), one geopetal cement, and 10 precipitated along karstic walls. The ages at 29 ± 1 Ma (Lower...
