Solar wind from the center of the Earth

High-precision noble gas analyses indicate that solar wind particles from our primordial Sun were encased in the Earth's core over 4.5 billion years ago. Researchers from the Institute of Earth Sciences at Heidelberg University ...

Deep diamonds contain evidence of deep-Earth recycling processes

Diamonds that formed deep in the Earth's mantle contain evidence of chemical reactions that occurred on the seafloor. Probing these gems can help geoscientists understand how material is exchanged between the planet's surface ...

Reading between the diamonds: Scientists expand deep carbon story

The high temperatures and pressures of the Earth's mantle forge carbon-rich minerals known as carbonates into diamond. But less is known about the fate of carbonates that travel even deeper underground—depths from which ...

A new, clearer insight into Earth's hidden crystals

Geologists have developed a new theory about the state of Earth billions of years ago after examining the very old rocks formed in the Earth's mantle below the continents.

Moon's largest crater holds clues about early lunar mantle

Despite our long history with Earth's closest celestial neighbor, much remains unknown about the moon, including about asymmetries between its near side and far side, for example, in crustal thickness and evidence of volcanic ...

Subduction may recycle less water than thought

When one tectonic plate dives beneath another at a subduction zone, it recycles huge amounts of water and other chemicals into Earth's mantle. The sinking plate carries seawater trapped in sediments and crust or chemically ...
