Abstract

The relief оf the rift zone of the South Atlantic Mid-Ocean ridge is presented by tectonic and magmatic morphostructures, the good example of which one can see in the segment between Ascention and Bode-Werde transform faults. Tectonic morphostructures with the clear cut rift valley are typical for the edge parts, which are joined to transform faults. Magmatic morphostructures are characteristic for the middle of the segment. This division of the morphostructure along the segment’s axial zone conforms to some theoretical magmatic camera models. Therefore geomorphological data can be important criterion for the solution of the inversed problems in geodynamics of oceanic crust.
