New Map of Proposed Mantle-Driven Topography Stirs the Pot
The role the deep Earth plays in creating topography is hotly debated. A new study uses subtle elevation changes around the globe as evidence that the mantle plays a key role in building topography.

Old Igneous Rocks Hold the Key to Crustal Thickness Evolution
The chemical composition of orogenic igneous rocks and their zircons is sensitive to crustal thickness and can be used to quantify the evolution of Moho depths beneath continents back in time.

Earth’s Lower Mantle Is Drier Than Previously Thought
Scientists have long known that the two layers of Earth’s mantle have different chemical compositions. Now, modeling shows that different water concentrations may keep them from mixing.

Krypton Isotopes Provide New Clues to Planets’ Pasts
To trace how crucial ingredients for life arrived at Earth, scientists track noble gases. Now, improved methods are drawing new clues from krypton, the most cryptic of noble gases.
