An analysis of Hawaii’s volcanic rocks revealed Earth’s core is leaking gold and other precious metals, a study found. The ...

Geochemists suggest that Earth's upper mantle varies in composition over kilometer-sized pockets. New research by Brown University geochemists provides new insights on the scale at which Earth's ...

Scientists Discover Two Massive Structures Deep Within Earth’s Mantle, Say It Could Be Remains of Ancient Planet For decades, ...

This sample, which is more than six times longer than the previous core of mantle rock, has given us a glimpse into the composition of this mostly inaccessible layer of the Earth. You can read ...

Earth is made up of several layers. Layers based on chemical composition are the core, mantle and crust. According to mechanical properties, Earth's layers are the lithosphere, asthenosphere ...

told Science Magazine that these samples can provide direct evidence for how ocean crust differs in composition from the upper mantle, better estimates of “the global composition of the bulk ...

Scientists still disagree about the composition of the deep mantle. There are odd structures near the core-mantle boundary called large low-shear velocity provinces (LLVPs), where seismic waves ...

Seismic imaging has exposed two massive zones hidden deep in Earth’s mantle. These giant blobs, known as large low-velocity ...

The oxygen fugacity (fO 2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived magmatic activity ...

Above the core is Earth's mantle, which is about 1,800 miles (2,900 km) thick. The mantle is not completely stiff but can flow slowly. Earth's crust floats on the mantle much as a piece of wood ...

This discovery was made by two independent teams and challenges the previous view that the mantle – which lies between the Martian crust and core – has a uniform composition and structure. The new ...

As well as offering new insights into mantle composition, the drill core gives us other glimpses into Earth's deep geology and the conditions that could have been involved in the origins of life.
