Abstract

Geophysical and geochemical study of the Pacific-Antarctic ridge between S65/W175 and S60/W150. The first objective was to contribute to the understanding and modelling of the mechanisms of ocean ridge functioning on the scale of the basic accretion unit (< 100 km). The second was to study the zoning of the upper mantle on various scales, through investigating the geochemical signature of rocks from the axial valley. This cruise falls under the framework of the Inter-Ridge programme and is the result of cooperation between IFREMER/DRO/GM, INSU (CNRS,IPG, GRGS), Washington State University, Scripps (University of California) and the University of Chiba (Japan).
