Along the Atlantic Tectonic Ring, several major geological structures become traceable. One of the clearest is the Greenland–Iceland–Faroe Ridge Complex, which forms an important North Atlantic segment of the system. Farther south and east, the ring also appears to correspond in a broad way with the Teisseyre–Tornquist Zone, as well as with the Adriatic region, the Red Sea, and the Afar triple-junction area, together with the main divergent boundaries of Africa.
On the western side of the system, its influence may be followed through the Antarctic Peninsula, the East Pacific Rise, the San Andreas system, the western Caribbean and Central America, and the Peru–Chile subduction complex. In this sense, the Atlantic Ring is not limited to the Atlantic Ocean itself, but extends into surrounding tectonic regions and connects with major plate-boundary systems on both sides of the ocean basin.
In geometrical terms, the Atlantic Ring appears to be centred on the Mid-Atlantic Ridge, together with its corresponding mantle division line in the Convection Rolls Model. This makes the Mid-Atlantic system the structural backbone of the ring. Around it, a broad set of convergent, divergent, and transform-related features seem to define a large-scale circular tectonic framework. Although some segments are more clearly expressed than others, the overall pattern suggests that the Atlantic domain may be viewed as one of the three major global tectonic rings, alongside the Pacific Ring of Fire and the proposed Indian Ocean Ring.
