The Meillon (Callovo-Oxfordian) and Mano (Tithonian) Formations are dolomitized carbonate reservoirs that actively produce oil gas (Aquitaine Basin, France). In this study, the dolomitization conditions of their counterparts exhumed in northwestern Pyrenees detailed using a combination field observations, petrography, fluid inclusion microthermometry, elemental isotopic geochemistry, U–Pb geoch...

High-amplitude changes in sedimentary δ 13 C characterize the Cretaceous system and have been proven useful for supra-regional chemostratigraphic correlation. In Cretaceous, these perturbations indicate large shifts between global carbon reservoirs that are usually caused by volcanic activity of igneous provinces, widespread deposition thick organic carbon-rich sequences and/or orbital paramete...

The Vaca Muerta Formation (Tithonian–early Valanginian) is the main source rock in Neuquén Basin and most important unconventional shale resource South America. In present study, organic geochemistry, electron microscopy basin petroleum system modelling (BPSM) were combined to evaluate properties related processes along a transect from early oil (east) dry gas (west) window. unit characterized ...

Lower Jurassic sedimentary successions in the Atlantic margin basins include several organic-rich intervals, some with source rock potential; time-equivalent units are also identified on- and offshore areas worldwide. Despite decades of research, it is still unclear which mechanisms lead to deposition sediments during Early Jurassic. The objectives this study construct a detailed temporal geogr...
