Skewed Subduction Shear Zones
A global reanalysis of both short- and long-term deformation clarifies how obliquity affects strain partitioning in convergent plate boundaries.
How to Build the World’s Highest Mountain
The rocks of Mount Everest’s peak made an epic journey from seafloor to summit.
Modeling the Long and Short of Subduction Zones
A new subduction model could reveal important insights about megathrust earthquakes.
Nevada tiene montones de litio. Esta es la razón.
Nevada se está convirtiendo en un gran productor de litio, gracias a la topografía, el clima y la serendipia geológica.
Scientists May Have Found Another Viscosity Shift in the Mantle
The proposed distinction could improve Earth models.
Compositional Anomalies Complicate Our Model of Mantle Convection
A new study expands on recent research which suggests that oceanic crust accumulates in the mid-mantle. The new seismological constraints advance our understanding of thermo-chemical planetary evolution.
Elementary, My Dear: Al & Be Give Evidence of Past Climate Change
10Be and 26Al concentrations in river sand reveal an increase in erosion rate in the Brazilian Highlands consistent with the Mid-Pleistocene Transition, a major climatic shift that occurred about 1 million years ago.
A New View of Deep Earth’s Carbon Emissions
Advances in plate tectonics research allow a deeper understanding of how greenhouse gases escape from within the planet.
