The Mozambique Ridge : Evolution of a Large Igneous Province and its implication for palaeocean circulation
New multi-channel seismic reflection data acquired in the southwest Indian Ocean is used to evaluate the basement structure and the origin of the southern Mozambique Ridge (MozR). Another objective of the interpretation of the data is to investigate the possible impact of the structure on palaeocean...
