The aim of this work is to constrain (1) whether exhumation of mantle rocks at mid oceanic ridges is compatible with the record of polarity reversals of the Earth magnetic field, (2) what is the origin and the processes responsible for the magnetic anomalies observed at magma-poor rifted margins and...
