118-121) Formation of LIPs is thought to be a geological consequence of superplume, a giant hot-rock nucleates rising through the Earth's mantle.
Projects address a diversity of research challenges, including imaging the African superplume seismic geostructure, analyzing geohazards, providing cleaner water through nanotechnology, developing better ways of interpreting meaning in languages, and advancing frontier fields such as angstrom-scale technologies, electron chemistry, and microfluidics.

Ultramafic igneous rocks from the Labrador Trough (Quebec) and the Thompson nickel belt (Manitoba) have been associated with a mantle superplume event at 1.
More recently Puffer (2002) pointed out that the plateau basalts are the most northerly products of a Late Neoproterozoic superplume centered on Sutton Mountain (Quebec) that also yielded basalts as far south as Virginia.
The superplume disrupted the magnetic field and put a strain on creatures living on the surface, but it was only the beginning.
Hence, the net result of the superplume events associated with the lower Aptian (OAE 1b) is distinguished by a general enhancement of the oxygen minimum level in the Tethyan realm and epicontinental seas where there was an increase in TOC, (up to 20+%), in the La Pena Formation, for instance.

The two superplumes, one beneath Hawaii and the other under Africa, likely have existed for at least 200,-000,000 years, explains Wendy Panero, assistant professor of earth sciences.
Washington, Dec 16 (ANI): Scientists have found that two superplumes of hot rock deep within the Earth are linked to the plate motions that shape the continents.
