Hunks of oceanic crust are squeezed inside the mantle of the earth



In Geology 101, the Earth’s interior is divided into neat layers, like a sugar-coated jaw crusher. But it turns out that parts of the planet’s middle layer may look more like peanuts in a caramel sea. Seismic data reveals that there may be hunks of oceanic crust stuck deep inside the planet’s floating mantle, creating large lumps in one of the slippery layers.

The authors of a new study discovered these “peanut snuff” inside the sticky mantle of East Asia. Their findings could, in addition to being deliciously exciting, have implications for models of how the sea crust is formed and moves.
