NEW DATA ON THE GEOLOGICAL STRUCTURE OF THE JUNCTION BETWEEN THE CAPE VERDE SEAMOUNT AND THE CAPE VERDE BASIN, CENTRAL ATLANTIC

Abstract

The regions of conjugation of continental rise with abyssal oceanic basins at the margins of the Atlantic — a transitional zone between continental and oceanic lithospheres—are still poorly studied in geological terms. In the course of expeditions conducted by the Geological Institute (Moscow), the structure of this zone was studied at the continental slope of Africa, south of the Cape Verde Islands. In this area, the continental rise widens sharply making up a near-latitudinal promontory that divides the abyssal Cape Verde Basin in the south and the Canary Basin in the north.
