Description :
This work determines the nature of the recent sedimentary filling in the Bay of Cadiz sea bottom and adjacent continental shelf and establishes the main controlling factors on the Holocene marine sedimentation. Bathymetric, geophysical and drilling data have been employed to prepare a detailed isopach map of the non-consolidated recent sedimentary cover. The general distribution of isopachs in this area is clearly influenced by these morphostructural lines, which controlled the sedimentary processes during the Holocene. This is coherent with the main regional neotectonic structures in the nearby continental area, and confirms their prolongation towards the marine domain.
