A unique rock formation in China holds clues that tectonic plates subducted, or went underneath other plates, during the Archean eon (4 billion to 2.5 billion years ago), just as they do nowadays, a ...

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 ...

Earth is a dynamic and constantly changing planet. From the formation of mountains and oceans to the eruption of volcanoes, the surface of our planet is in a constant state of flux. At the heart of ...

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 ...
