Scientists have traced past pathways of tectonic plates back a billion years using computer models, with intriguing results. Incorporating geologic data as a check on model output, however, has proven tricky.
Every summer, a low-oxygen pool settles off Canada’s western coast. A new study uses robust modeling to track the origins of the dense water.
Numerical models provide quantitative constraints on topography lost to erosion, showing how the sediment influx in a sedimentary basin reflects its tectonic and topographic evolution.
Helium isotopes found in water samples provide a snapshot of what lies beneath the plateau and stimulate debate within the geosciences community.
Living in Geologic Time: The making, breaking, and backpacking of North America’s Continental Divide.
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.
How have these continental relics from Earth’s early history survived the plate tectonic mixing machine?
A decade-long research collaboration has revealed that the split between Africa and North America roughly 200 million years ago was more drawn out than previously thought.
Geoscientists have long been trying to answer the complicated questions of how and why Earth’s continents formed. New research suggests a solution that surprised even the investigators themselves.
Seismic reflection images combined with petrological data provide new constraints on the nature of the basement in the enigmatic Australia-Antarctic oceanic-continent transition zone.
