Researchers have combined numerical modeling of dislocation glide and results from diffusion experiments to revisit the rheology of wadsleyite, ringwoodite and majorite garnet under geological strain ...
Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same. A ...
At a depth of 2900 kilometres, the layer between the Earth's mantle and its core has always intrigued geophysicists because they are unable to explain the seismic data it generates. Researchers in the ...
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 ...
Slow roiling convection currents deep within Earth's mantle, which are associated with the movements of tectonic plates, also ...
