The geological materials in Earth's lowermost mantle control the characteristics and interpretation of seismic ultra–low velocity zones at the base of the core-mantle boundary. Partial melting of the ...

Crystalline brown-hornblende mylonite, with a composition similar to some basanites and nephelin-ites, was crushed and reacted with excess water and with no water added (about 2% water present) in ...

The South Pole-Aitken (SPA) is the largest and deepest basin on the Moon, theoretically opening a window into the lunar lower crust and likely into the upper mantle. However, compositional information ...

Humble oxygen is more than just a building block of life. The element could also help scientists sneak a peek into the innards of planets orbiting faraway stars, a new study suggests. Laboratory ...

Today's Earth is a dynamic planet with an outer layer composed of giant plates that grind together, sliding past or dipping beneath one another, giving rise to earthquakes and volcanoes. Others ...

Making strong bricks on Earth is hard. Making strong bricks on the moon is harder. But some researchers in a University of Texas at San Antonio laboratory are working to make it possible. They’re ...
