Bouvet triple junction

It is named after Bouvet Island, which lies about 250 km (160 mi) to the east.

[6] Up to 10 million years ago this third junction of the Mid-Atlantic Ridge and the two deep transform valleys of Conrad and Bouvet met in one point.

[7] Conrad transform, known as the Conrad fracture zone,[2] stretching to the west, connected the end of the Mid-Atlantic Ridge to the South American-Antarctic Ridge.

Bouvet transform, known as the Bouvet fracture zone,[2] linked it to the Southwest Indian Ridge on the eastern side,[7] and this is known to be the oldest part of the current triple junction at 8 Ma.

New spreading sections of the South American-Antarctic Ridge and the Southwest Indian Ridge are growing northward from the eastern end of Conrad transform and the western end of Bouvet transform respectively, striving for the shifting triple point.
