Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought. New research led by scientists at the University of Wisconsin–Madison has ...
The history of Earth's continents might be different from what we first thought. The most popular theory of how the continents formed billions of years ago may not be right, according to a paper in ...
Africa's ground is shifting. Tectonic forces are tearing the continent apart along the East African Rift. Satellites and GPS ...

Scientists just uncovered that Earth had continents and mountains way before plate tectonics
Microscopic zircon crystals discovered in Western Australia suggest that Earth may have had continental crust as early as 4.4 ...
The mechanisms underlying two important phenomena in the Archean—the emergence of continental crust and the presence of an exceptionally strong geomagnetic field—remain poorly understood. Notably, ...
A comprehensive examination of the oldest minerals on the planet, microscopic grains of zircon more resistant than diamond, has provided the strongest chemical evidence to date that processes of ...
The formation of the Earth’s continents occurred during a fiery afterbirth known as the Archean Eon, which stretched from 4 billion to 2.5 billion years ago. It was in this bubbling cauldron of ...
Computational modeling shows that plate tectonics weren't necessary for early continents. The formation of Earth's continents billions of years ago set the stage for life to thrive. But scientists ...
Olivine cumulate from the Weltevreden Formation showing that although these cumulates are significantly altered, they still contain preserved unaltered olivine cores (microscopic image taken in ...
