Objective Geophysical survey of 2 sections of the South West Indian Ridge from the axis to a distance of about 100 km, corresponding to more than 10Ma. Profiles were 4 miles apart to ensure correct interpretation of gravimetry and magnetism data. The first zone studied was located around 38S and 50E, and was along a straight axis with shallow depths. The second zone was located around 34S and 56E, and was along a highly fragmented and very oblique axis.
