摘要

According to the plate tectonics concept, Atlantictype oceanic margins belong to tectonically passive margins. However, many observations indicate that some segments of these margins are characterized by intense tectonic and magmatic activity [1]. Cruise 23 of the R/V Akademik Nikolai Strakhov was accomplished in one such region at the junction of the continental slope and Atlantic Ocean structures south of the Cape Verde Islands (Fig. 1). The scientific supervisors of the cruise were Academician Yu.M. Pushcharovsky and Yu.G. Leonov. In the cruise, the bottom topography and acoustic profiling were studied with a RESON (SeaBat 8150) multibeam echo sounder, continuous seismic profiling (CSP) was carried out, magnetic and gravitation fields were measured, and dredging and sampling of bottom sediments were also conducted.
