At https://www.livescience.com/planet-earth/geology/africa-is-being-torn-apart-by-a-superplume-of-hot-rock-from-deep-within-earth-study-suggests …. researchers have found evidence Africa is being split apart because of a deep mantle super plume of hot rocks beneath the East African Rift System. Is this another spike in the wheel of Plate Tectonics theory?
Geologists are suggesting gases at the Meengal geothermal field in central Kenya have a chemical signature that comes from deep inside Earth’s mantle. The signature matches those of volcanic rocks to the north, in the Red Sea, and to the south, as far away as Malawi. Are all these places sitting on the same deep mantle rocks?
The lithosphere, Earth’s rocky crust, or shell, has been gradually breaking apart across the Rift System for around 35 million years – a geochronological calculation. It has left behind a network of deep valleys that carve through a large region, from the Red Sea to Mozambique. No mention is made of the extension into the Levant – the Rift valley from Aqaba to the Dead Sea, river Jordan, and Lake Tiberius. There is no hint of the Levant splitting apart. However, one may wonder if Malagasy, what was known as Madagascar, was an earlier lump of Africa that went walk about.
