A mass of oceanic crust is digging into the Earth’s mantle

In Geology 101, like a sugar-coated jawbreaker, the interior of the Earth is divided into neat layers. However, some of the Earth’s middle layers turned out to be like peanuts in the sea of ​​caramel. Seismic data reveal that oceanic crust masses are anchored deep into the planet’s liquid mantle, forming large masses in one of their smooth layers.

The authors of the new study found those “peanut chunks” in the sticky mantle beneath East Asia. Their findings, in addition to being very interesting, can affect models of how the oceanic crust is formed and moved.
