High-resolution seismic models of the Nova Scotia margin reveal a role for magmatism in continental breakup, even at magma-poor sections of the eastern North American margin.
Plate tectonics
Radiometric Dating Sheds Light on Tectonic Debate
The emplacement of the Samail Ophiolite in Oman has been a source of disagreement among geologists. New state-of-the-art research offers a fresh perspective on its timing and geometry.
Recovering Mantle Memories from River Profiles
Researchers use a closed-loop modeling strategy to validate regional uplift patterns recorded in river profiles across the African continent.
A Monsoon-Filled Reservoir Might Have Nudged a Fault to Fail
New research examines whether a sudden increase in water loading in Pakistan’s Mangla Dam might have been connected to the 2019 New Mirpur earthquake.
Oldest Pole Reversal Shows Early Earth Was Well Suited for Life
Australian rocks 3.25 billion years old preserved the oldest signs of Earth’s stable magnetic field and quickly moving crust, critical elements of life’s evolution.
Rock Structure Explains Slow Seismic Waves
New findings contrast with a prevailing hypothesis for low seismic velocity in subduction zones.
Unearthing the Cause of Slow Seismic Waves in Subduction Zones
Researchers look to the fossil rock record to unearth the driving forces for variable seismic speed through subduction zones.
The Birth, Growth, and Death of Continents
There are various explanations for how the Earth’s continents form, develop, and change but challenges remain in fully understanding the driving forces behind plate tectonics on our planet.
Measuring Sea Level Rise Along the Coast
Scientists created a global map of vertical land motion to show how the solid ground is moving relative to the planet’s rising seas.
