Tectonics of the Iberian continental margins and abyssal plains

From Continental Drift to Plate Tectonics

SINCE THE l6TH CENTURY, CARTOGRAPHERS HAVE NOTICED THE jigsaw-puzzle fit of the continental edges. Since the 19th century, geologists have known that some fossil plants and animals are extraordinarily similar across the globe, and some sequences of rock formations in distant continents are also strikingly alike. At the turn of the 20th century, Austrian geologist Eduard Suess proposed the theor...

The coupling of Indian subduction and Asian continental tectonics

In order to understand the potential controls on Asian tectonics during the subduction of the Tethys and Indian lithospheres, we reconstruct the coupled subduction-continent deformation history using tomographic imaging, kinematics constraints and numerical modeling. The global P-waves tomographic images of the mantle below the India-Asia collision zone provide constraints on the deep structure...

Numerical Geodynamic Modeling of Continental Convergent Margins

Transience and Persistence in the Depositional Record of Continental Margins

Continental shelves and coastal plains are large persistent depositional landforms, which are stationary (nonmigrating) at their proximal ends and characterized by relatively steady long-term growth. In detail, however, their surface form and stratigraphic record is built of transient freely migrating landscape elements. We derive the timescales of crossover from transient to persistent topogra...

The deep-sea Buccinoidea (Gastropoda: Neogastropoda) of the Scotia Sea and adjacent abyssal plains and trenches

Four new genera and species of buccinoidean gastropods, S/HW;»cr/nmn s/p/f/imiff/r new genus, new species: Dn^M/wof/on/ff.s /o/z/f/Nf/c new genus, new species; Afff^zn/wcr/HMMi cof/icdnf/f new genus, new spi-cies; and (x/ifionro n/rWw new genus, new species, are described from the Scotia tectonic plate and adjacent alwssal plains.
