Stresses Associated with Continental Break-Up,lop as the lithosphere thins are not large enough to have much influence on the tectonic development. A source of sufficiently large renewable extensional stress to cause lithospheric failure is the hot, low-density upper mantle of the type associated with a plume. Widespread extensional stress may

Nature of Thin Crust Across the Southwest Greenland Margin and its Bearing on the Location of the Oe of thin upper crust overlying a serpentinized mantle. The nature of the crust in this zone, however, remains in dispute. Interpretation that this is thinned continental crust is in conflict with the interpretation based on magnetic data which suggest it to be oceanic. The magnetic data from this r

Anisotropy Measurements and the Deep Structure of a Passive Margin: Southwestern Greenland,opy. Seismic anisotropy estimation can constitute an additional constraint in the determination of the mineralogical composition of the deep crust from indirect seismic measurements. Resolution analysis studies reveal that p-and S-wave velocity measurements derived from wide-angle seismic reflection

Rifted Continental Margin off Mid-Norway,agmatic dimensions of the Late CretaceousPaleocene rift episode which terminated with complete lithospheric separation and massive igneous activity during breakup and initial sea floor spreading. The breakup was preceded by a 15-20 m.y syn-rift phase developing a more than 2600 km long and about 300

The Edge Experiment and the U.S. East Coast Magnetic Anomaly,d seismic refraction data. These results are combined with magnetic total intensity data in order to establish the origin for the East Coast Magnetic Anomaly (ECMA) and to hypothesize about geological events taking place at the time that opening was initiated in the North Atlantic..Prominent seaward

Structure of Atlantic Oceanic Crust Around Chron M16 from Deep Seismic Reflection Profiles,f the acquisition parameters and of the reflective patterns, allows us to perform an identical post-stack processing sequence in order to interpret jointly the three data-sets. Despite the scattered energy produced at the contact between the sedimentary cover and the top of the igneous basement, a r

Nature, Structure and Evolution of the Ocean-Continent Boundary: The Lesson of the West Galicia Mar from the oceanic domain to the passive margin: basaltic seafloor, sheared and serpentinized mantle rocks cropping out on the “peridotite ridge”, mylonitized underplated gabbro, and upper continental crust resting on a strong seismic reflector considered to be a detachment..The geological and geophy

Detachment Faulting and Continental Breakup: The S Reflector Offshore Galicia,fault blocks are underlain on time sections by an undulating group of bright reflections, the so-called Galicia S reflector. We use a variety of advanced processing techniques to constrain the nature of S, including pre stack depth migration to construct detailed velocity models of the section overl
