A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published today in AGU Advances, AGU’s ...
Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...
Observations indicate that plate tectonics began before any currently known structural geological record on Earth Identification of the oldest preserved pieces of Earth’s crust in southern Greenland ...

A small team of geologists and seismologists at the California Institute of Technology has found evidence via computer modeling that suggest giant blobs of material near the Earth's core, believed to ...

Tectonics is the study of the structural geology of the Earth and other planetary bodies, and the local and regional processes that created that rock geometry. This includes the movements of the Earth ...

New research analyzing pieces of the most ancient rocks on the planet adds some of the sharpest evidence yet that Earth's crust was pushing and pulling in a manner similar to modern plate tectonics at ...
Ancient rocks reveal water moved deep underground over three billion years ago. This process, called dripduction, occurred ...
Direct evidence of the movements of tectonic plates has been found in some of the world’s oldest rocks, in the Pilbara Craton, Western Australia. This evidence dates back 3.5 billion years; the ...
