  abstract = {{O}ceanic crust formed at slow-spreading ridges is currently subducted in only a few places on {E}arth and the tectonic and seismogenic imprint of the slow-spreading process is poorly understood. {H}ere we present seismic and bathymetric data from the {N}ortheastern {L}esser {A}ntilles {S}ubduction {Z}one where thick sediments enable seismic imaging to greater depths than in the ocean basins. {T}his dataset highlights a pervasive tectonic fabric characterized by closely spaced sequences of convex-up {R}idgeward-{D}ipping {R}eflectors, which extend down to about 15 km depth with a 15-to-40 degrees angle. {W}e interpret these reflectors as discrete shear planes formed during the early stages of exhumation of magma-poor mantle rocks at an inside corner of a {M}id-{A}tlantic {R}idge fracture zone. {C}loser to the trench, plate bending could have reactivated this tectonic fabric and enabled deep fluid circulation and serpentinization of the basement rocks. {T}his weak serpentinized basement likely explains the very low interplate seismic activity associated with the {B}arbuda-{A}negada margin segment above. {P}ervasive detachment faults in the oceanic basement at the {NE} {A}ntilles {S}ubduction {Z}one could enable deep fluid circulation and serpentinization and partly control the reduced interplate seismicity, according to seismic reflection and bathymetric data},
