Earth's mantle

Simulation of an asteroid impact on the ancient Earth and of basalt-rich and -poor regions in the mantle.

The asteroid bombardment that delayed the formation of continents on the ancient Earth

New research suggests that asteroid impacts during the Hadean period were not just local, short-lived events. The energy they delivered deep into the Earth heated the mantle, increased crustal melting and recycling, and delayed the emergence of

Analysis of gases from hot springs in a frozen rift indicates the intrusion of gases originating from the Earth's mantle. Researchers estimate that this may be an early stage of a continental rift in South Africa.
In 2020, researchers installed one of 1,800 temporary magnetotelluric stations in Grant County, New Mexico, to test the electrical conductivity of rocks deep below the surface. Credit: Sarah Watson / Green Geophysics

Scientists observed for the first time how atoms in a magnesium oxide molecule change and dissociate under extremely harsh conditions, and gained new insights into this important mineral in the Earth's mantle that is known to influence the formation of planets

The new research from Calcutta suggests that remnants of that ancient planet known as Theia are still inside the Earth and explain the origin of the "lumps" near the core-mantle boundary. Other remnants of it coalesced to form the
