Segmentation of the Mid-Atlantic Ridge between 24° N and 30°40' N
摘要：
THE Mid-Atlantic Ridge (MAR) extends for over 12,000 km from Iceland to the Bouvet Triple Junction in the south Atlantic. Most of our knowledge of the geology of this slow-spreading centre comes either from widely spaced low-resolution echo-sounding lines or from detailed studies of small areas using deep-towed instruments or submarines. High-resolution multibeam bathy-metryhas been insufficient to define the variability of accretionary processes along this plate boundary. Here we present the results of a recent investigation of a800-km-long section of the MAR carried out using the multibeam echo-sounder SeaBeam. Analysis of these data reveals the scale and nature of the segmentation of the MAR between the Kane Fracture Zone (24° N) and latitude 30°40' N.
