... at the continental margin in the Ghana Ridge region (Figs 13 & 14 ). A small segment of the distal margin in the offshore Ivory Coast shows a clear pull-apart control of the continental break-up and a significant warming-up of the distal margin around its development (Fig. 13 ). The former is documented...
