The present paper reviews the geological development of the Faroes part of the NE Atlantic Margin in the Cenozoic Era. The Faroes area is located west of the post-Caledonian rift basin system formed in the Devonian after the collapse of the Caledonian mountains. Tectonic movements and plate reorganizations during several phases have strongly influenced sedimentation and erosion along the Caledo...
Wellbore collapse, seafloor subsidence, and seismic events are some of the main technical societal issues related to deformation producing chalk reservoirs. The triaxial tests represent valuable input data for geomechanical rock physics models that document properties mechanical response under in situ conditions. Most experimental studies from Upper Maastrichtian Tor Fm. is oil-bearing unit Nor...
Cold-water coral (CWC) ecosystems occur worldwide and play a major role in the ocean's carbonate budget and atmospheric CO2 balance since the Danian (~65 m.y. ago). However their temporal and spatial evolution against climatic and oceanographic variability is still unclear. For the first time, we combine the main macrofaunal components of a sediment core from a CWC mound of the Melilla Mounds F...
Meyers, P.A., 1992. Changes in organic carbon stable isotope ratios across the K/T boundary: global or local control? In: S.A. Macko and M.H. Engel (Guest-Editors), Isotope Fractionations in Organic Matter: Biosynthetic and Diagenetic Processes. Chem. Geol. (Isot. Geosci. Sect. ), l 01: 283-29 I. A global shift in carbonate carbon j~3C-values from heavier values in the Maastrichtian to lighter ...
