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 in the open access journal AGU ...

Map of the Earth showing tectonic plates. Early Earth likely had no plate tectonics, but a solid outer crust with no tectonic activity covered the entire planet. After being broken up by convection ...

Researchers have discovered the world's oldest known arc-slicing fault in Australia, intensifying the debate over the origins of plate tectonics. When you purchase through links on our site, we may ...

Minerals suggest large blocks of Earth’s crust moved around as early as 3.2 billion years ago Modern plate tectonics may have gotten under way as early as 3.2 billion years ago, about 400 million ...

Plate tectonics – the drifting of continents – may have got under way at least 3.2 billion years ago and could have played a part in the evolution of life, a study of the magnetism of ancient rocks ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

Researchers analyzing ancient deposits in Australia found evidence that Earth's layers started to get mixed up — a fingerprint of plate tectonics — about 1.3 billion years after the planet formed.

Plate tectonics may be unique to Earth and may be an essential characteristic of habitable planets. Estimates for its onset range from over 4 billion years ago to just 800 million years ago. A new ...
