Ultraslow spreading ridges are divergent plate boundaries, which spread apart with less than 20 mm/yr. Their appearance is very rugged, with steep rift flanks, numerous normal faults and discontinuous volcanic activity at discrete volcanic centres - drastically different from ridges which spread fas...
