[theories abound]
"... KEY POINTS
• Employing time dependent global mantle convection models since the Cretaceous. [the authors] simulate the origin of the enigmatic Indian Ocean geoid low
• Plumes forming along the edges of the African Large Low Shear Velocity province (LLSVP) control the regional geoid in the Indian Ocean
• These plumes, in turn are generated by lower mantle Tethyan slabs that perturb the African LLSVP…”
