African superswell
From Wikipedia, the free encyclopedia
The African superswell is an extraordinary uplift of the African continent, particularly its southern half; southern Africa on average lies a full kilometer above sea level, with seemingly anomalous uplifts extending well into the south Atlantic ocean.[1][2]
The superswell is a relatively recent phenomenon, probably beginning between 5 and 30 million years ago.[3] A proposed cause of the superswell is a mantle plume, though this hypothesis is controversial and the origin of the superswell remains an active area of research.[4]
