The Mid-Atlantic Ridge (MAR) at 26° S is an asymmetrical slow spreading ridge (Niu et al., 1994). The ridge segment between 25°40′ and 26°35′S is about 100 km long, and it is bounded by the Rio Grande Transform to the north, and the Moore Fracture Zone to the south. There is a topographic high near the centre of the ridge segment, in where the 26°S hydrothermal area is located. To the both sides of the ridge segment distribute welldeveloped axial rift valley of typical slow spreading ridge and numerous axially arranged topographic high.
