Última Along-arc segmentation and interaction of subducting ridges with the Lesser Antilles Subduction forearc crust revealed by MCS imaging ArchiMer Laigle, Mireille; Becel, Anne; De Voogd, Beatrice; Sachpazi, Maria; Bayrakci, Gaye; Lebrun, Jean-frederic; Evain, Mikael; "Thales Was Right" Seismic Reflection working group. We present the results from a new grid of deep penetration multichannel seismic (MCS) profiles over the 280-km-long north-central segment of the Lesser Antilles subduction zone. The 14 dip-lines and 7 strike-lines image the topographical variations of (i) the subduction interplate décollement, (ii) the top of the arcward subducting Atlantic oceanic crust (TOC) under the huge accretionary wedge up to 7 km thick, and (iii) the trenchward dipping basement of the deeply buried forearc backstop of the Caribbean upper plate. The four northernmost long dip-lines of this new MCS grid reveal several-kilometres-high topographic variations of the TOC beneath the accretionary wedge offshore Guadeloupe and Antigua islands. They are located in the prolongation of those... Tipo: Text Palavras-chave: Lesser Antilles Subduction Zone; Reflection seismics; Deep outer forearc crust; Backstop; Seismogenic megathrust fault.
