Última La cinématique de l'Atlantique Nord : la question de la déformation intraplaque ArchiMer Fidalgo González, Luis. The main features of geodynamic evolution in the North Atlantic and the lithospheric plates surrounding it have been known for a quarter of a century now. However, a number of questions raised by the first models published have still not been clearly answered in detail. Among them, the difficulty in adjusting the domain to the north and the south of the Faeroe-Iceland-Greenland ridge should be highlighted. This study addresses the issue by using fracture zones as the main data for our reconstructions. We show that they accurately bound the kinematical reconstructions. They also enable kinematical reorganisation periods to be studied on the scale of oceans, as well as their duration. Reconstructions carried out on these bases confirm the existence of...

Ano: 2001 URL: http://archimer.ifremer.fr/doc/2001/these-1205.pdf Modeling of the bottom water flow through the Romanche Fracture Zone with a primitive equation model - Part I: Dynamics ArchiMer Ferron, Bruno; Mercier, Herle; Treguier, Anne-marie. This paper investigates the dynamics of the Antarctic Bottom Water (AABW) flow through the Romanche Fracture Zone (RFZ) in a primitive equation model with a high horizontal and vertical resolution. Two examples of Rows over simple bathymetries show that a reduced gravity model captures the essential dynamics of the primitive equation model. The reduced gravity model is then used as a tool to identify what are the bathymetric structures (sills, narrows) that mostly constrain the AABW flow through the RFZ. When only these structures are represented in the primitive equation model, the AABW how is shown to be coherent with observations (transports, density and velocity structures).

Ano: 2000 URL: http://archimer.ifremer.fr/doc/2000/publication-802.pdf New gravity and magnetic anomaly maps in the Taiwan-Luzon region and their preliminary interpretation ArchiMer Hsu, Shu-kun; Liu, Char-shine; Shyu, Chuen-tien; Liu, Shao-yung; Sibuet, Jean-claude; Lallemand, Serge; Wang, Chensung; Reed, Donald. We have compiled new free-air gravity anomaly (FAA) and magnetic anomaly maps, shedding light on the tectonics in the Taiwan-Luzon region. To have a suitable datum level for both the available gravity and magnetic anomaly data, the set of data from an ACT cruise, conducted during May 27 to June 21, 1996, was chosen as a reference. Based on the cross-over error analysis, all the other data were adjusted accordingly. Some satellite-derived, airborne or land data were also added to the compilation to obtain better coverage. Several major new insights into the Taiwan-Luzon region are revealed by the new maps. (1) A prominent NE-SW trending belt of gravity and magnetic anomalies is present in the onshore and offshore areas of southwestern Taiwan. The Peikang...

Ano: 1998 URL: http://archimer.ifremer.fr/doc/00447/55859/58057.pdf Un modèle général de d'évolution de l'océan indien ArchiMer Sahabi, Mohamed. The last global synthesis of the evolution of the Indian ocean which satisfactorily describes the kinematics of the five major plates, up to the initial stages, dates back to Norton and Sclater [1979]. Although the most recent phases of evolution have been largely detailed, in particular in the proximity of the triple junction, the initial stages of evolution have been generally described by models quite speculative and generally only constrained by pairs of plates. The recentmost gravity data based on the altimetric satellites SEASAT, GEOSAT and ERS1 [Sandwell and Smith, 1992] give an homogenoeus image of sea-floor topography. These data, declassified to the south of 30°S, reveal previously unknowkn features of the sea-floor fabric and allow to further...
