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.
Although shallow magma storage at Erta Ale volcano hints at a rift-to-ridge transition, the tectonic future of the Afar region is far from certain.
In 2017, an ocean research team launched an unprecedented effort to understand what drives ocean currents in the overlap regions between surf zones and continental shelves.
Two years of mooring observations at the edge of the continental shelf show that wind stress and upwelling control the inflow of some of the warmest water observed at an ice shelf front in Antarctica.
Evidence from collision zones suggests that the high temperatures that create regional zones of metamorphic minerals occur in wide, hot back arcs prior to continental collision deformation.
New data synthesis suggests that varying rates of trench retreat along the margin of the Gondwana supercontinent were responsible for the curvature of the Tasmanide mountain chains.
