Detailed structural, interpretátioh of a network of high-resolution seismic lines runnig across, , and along the continental shelf of Faro (south-lberian Atlantic margin) provides evidences of recent deformation structures associated with the Africa-Eurasia plate boundary. In these seismic profiles, palm-tree type flower structures interpreted as strike-slip faults affect the non-consolidated Holocene muddy shelf deposits and the underlying semi-cemented sandy shelf-wedges of the Pleistocene units. These structures are lined up following a ENE-WSW. direction, associated with the existence of a deeper dextral transcurrent basement fault with recent active seismicity between the southern Coringe Bank, Horseshoe Plain, Faro continental shelf and northern of Guadalquivir basin
