Geologists have discovered remnants of Earth's mantle that have persisted for over 2.5 billion years. The ancient rocks were less oxidized than modern ones, indicating that they were exposed to ...

Mantle's Cave is located in Dinosaur National Monument in northwestern Colorado, just south of the Yampa River. It is a large, vaulted, north-facing cave 100 m long x 40 m wide x 33 m in height, ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

The Earth’s mantle, a massive layer of rock beneath the crust, is the “engine” of plate tectonics. Stretching nearly 2,900 kilometers deep, it shapes much of the planet’s geology and ...

Scientists have uncovered potential remnants of Earth's ancient crust, often referred to as ‘sunken worlds,’ hidden deep within the mantle.And this was possible because of a new way of mapping ...

It creates the Earth's magnetic field and is about 1,400 miles (2,300 kilometers) thick. The next layer is the mantle. Many people think of this as lava, but it's actually rock. The rock is so hot ...

The next layer, the mantle, stretches about 1,800 miles (2,900km) below Earth's surface. The mantle contains both magma, or molten rock, and slowly-moving solid rock. Earth's innermost layer is ...
