Tectonic map of the Earth. The first continental crust on Earth formed more than 3 billion years ago. Likely the first fragments formed by partial melting and re-crystallization of the primordial ...

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 ...
At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from belowground force ...
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 ...
Hell, or something like it, may be a little closer than we thought. As a new study published in Nature Geoscience reveals, geologists at Cornell and the University of Texas have discovered a “hidden” ...
An enduring question in geology is when Earth’s tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some ...
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 ...
Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...
BUFFALO, N.Y. — At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from ...
