Аннотация

178 tectonic mountains are known from the axial area of the Mid-Atlantic Ridge between 58°30'N and 40°N (1300 miles along the axis, 822 000 km); the mountain area composes about 53% of the whole area, the rest surface presenting the rift valley floor and other longitudinal and transversal valleys. Only rare mountains are found at the ridge's flanks.

Four types of tectonic mountains are distinguished, differing in their base area: l – less than 1000 km², 2 – 1000 to 3000 km², 3 – 3000 to 6000 km², 4 – more than 6000 km². The axial zone is subdivided into 5 morphological regions according to the mountains types frequency.
