Abstract

[1] Distinctive features of the poorly studied MAR segment between 5^o and 7^o18' N are discussed with the use of bathymetric maps (based on surveying with a Simrad EM-12S multibeam echosounder), Bouguer anomaly maps, and slope angles. The comprehensive interpretation of these data made it possible to reveal the complex structures of the rift zone and the active parts of the fracture zones. A system of northwest strike-slip faults was discovered.
