Two competing paradigms explain these cataclysms, either by the splitting of tectonic plates at the Earth's surface or by the impacts of hot currents, called mantle plumes, from the planetary interior.
Together, they will launch 50 more MERMAIDs in the South Pacific to study a mantle plume underneath Tahiti.
That's where the mantle plume theory has come in, although it may not stick around for long.
Hot spots offer a window into the depths of Earth, as they mark the tops of mantle plumes that carry hot, buoyant rock from deep Earth to near the surface and produce volcanoes.
The geochemistry and Sr-Nd isotope composition of magmatic rocks, combined with moderate degrees of stretching ([beta] = 1.1 to 1.3), suggest that magmatism in the Pripyat-Dnieper-Donetsk Rift was triggered by the upwelling of a thermally and geochemically anomalous mantle plume in late Devonian times (Wilson & Lyashkevich 1996).
Twoway exchange between the Easter mantle plume and the Easter Microplate spreading axis.
"There are all these little slivers of continent that may peel off continents when the hotspot of a mantle plume passes under them," Hartz said.
The continental margins of the two antipodal large low shearvelocity provinces (LLSVPs) under Africa and the Pacific are favourable locations for the episodic initiation of large thermal upwelling (mantle plume).
It is suggested that these Late Cretaceous intra-plate volcanics may be related to the mantle plume activity of the Reunion hotspot, and were erupted during the passage of Ceno-Tethys ocean floor prior to the passage of the Indian plate over it.
The lack of a large eruptive volume or a thermal swell argues against a mantle plume origin for the TWVF.
