00925njm 22002777a 4500 dc Druet Vélez, María author Muñoz Martín, Alfonso author Carbo Gorosabel, Andrés author Álvarez García, Juan author Llanes Estrada, María Pilar author 2004 Since 2001 marine gravity data have been collected on the North Atlantic Ocean around Galicia Mar,-,in. The aim of this paper is the analysis of the Bouguer anomaly map of the west margin of Galicia and the modelling of the ocean-continent boundary in this area. Very high Bouguer anomaly values have been obtained for this region, specially in the oceanic trust of the Iberian Abyssal Plain. A gravity low is related to the Galicia Bank continental block, and relative positive elongate highs correspond with the Peridotite Ridge and the Galicia Interior Basin. The two gravity models presented here, based on seismic refraction and reflection profiles, have allowed the characterization of the gravity limit between oceanic and continental trust in this margin. This limit is located 15 km eastwards in the northern profile 1, from the previous proposed limit based on sedimentary criteria. 1576-5172 https://hdl.handle.net/20.500.14352/52552 http://www.sociedadgeologica.es/publicaciones_geotemas.html Modelización gravimétrica de la transición entre corteza continental y oceánica en el margen oeste de Galicia
