Scientists have identified two massive thermochemical formations at Earth's core-mantle boundary that refine understanding of ...

Southwest Research Institute’s Dr. Simone Marchi collaborated on a new study finding the first geophysically plausible scenario to explain the abundance of certain precious metals — including gold and ...

Earth's hot, gooey center and its cold, hard outer shell are both responsible for the creeping (and sometimes catastrophic) movement of tectonic plates. But now new research reveals an intriguing ...

Deep inside Earth, far below the crust and mantle we learn about in school, two colossal structures loom above the core like ...

July 5, 2022 – Researchers supported by the US Department of Energy’s (DOE’s) Exascale Computing Project (ECP) have integrated the super-parameterization technique for modeling moist convection into ...

Some mountains in "mobile belts" -- regions of crustal fragments, such as in the Mediterranean, the Rockies, and the Himalayas -- can rise due to upward pressure from the semi-liquid mantle. The study ...

A model for convection in the upper mantle of the Earth comprising two flows, one of percolating melt fluid (which need be no more than a small volume fraction in the intergranular channels of ...

The boundary between Earth's core and mantle is home to isolated pockets of rock which scientists have been unable to explain up until now. A team led by geoscientists from Arizona State University ...

ABSTRACT This paper reports on the application of the cloud-resolving convection parameterization (CRCP) to the Community Atmospheric Model (CAM), the atmospheric component of the Community Climate ...

This schematic illustrates the most geophysically plausible explanation for the abundance of HSE metals present in the Earth’s mantle. During the long period of bombardment, impactors would strike the ...
