Earth's mantle: New numerical tool describes rock deformation
Although solid, the rocks of the Earth's mantle deform very slowly. Professor Patrick Cordier's team at the Materials and Transformation Unit (Université Lille, France) has developed a model that makes it possible, over ...

Upside-down answer for deep Earth mystery: Clues point to 'density trap' in early mantle
(PhysOrg.com) -- When Earth was young, it exhaled the atmosphere. During a period of intense volcanic activity, lava carried light elements from the planet's molten interior and released them into the sky. However, some light ...

What goes down, must come up: Geoscientists offer new model for degassing of Earth's mantle
A new analysis of the processes that constantly stir the Earth's deep mantle is helping to explain how the mantle holds onto a portion of ancient noble gases that were trapped during the Earth's formation.
