Microcontinents in the Atlantic ocean

Fragments of continental structures are widespread in the North and South Atlantic and almost absent in the central segment of the ocean. This implies that the fragments are related to the geodynamics of the surrounding continents. The fragments are subdivided into two groups: microcontinents and submarine prominences of marginal continental blocks. Both groups are briefly characterized in this paper, and views on mechanisms of their formation are expressed. In my opinion, there is a good reason to believe that this line of research makes a substantial contribution to mobilistic geotectonics.
