Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

The colossal movements of tectonic plates shape our world, influencing the composition of Earth’s atmosphere, the planet’s protective magnetic field and perhaps even the flourishing of life. Now ...

Beneath the American Midwest, on the continent of North America, the underside of Earth's crust is dripping into the planetary interior. There, blobs of molten rock are coalescing in the upper mantle ...

Scientists discovered a crack under the sea off Vancouver Island, NFZ in Cascadia region, that could alter Pacific subduction.

Models of North China Craton deformation since the middle Jurassic, showing phases of flat slab subduction (a, b) and rollback (c, d). Key: overriding plate (O), downgoing plate (D), trench (T), ...

Stable parts of the Earth's crust may not be as immovable as previously thought. While much of the crust is affected by plate tectonic activity, certain more stable portions have remained unchanged ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

CORVALLIS, Ore. — Researchers at Oregon State University have completed a mammoth project to create a 3-D map of electromagnetic energy in the Earth's crust across the continental U.S. What began as ...

In the modern world, a reliable supply of hydrogen gas is vital for the function of society. Fertilizer produced from hydrogen contributes to the food supply of half the global population, and ...

Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...
