The Ontong Java and Manihiki oceanic plateaus are believed to have formed through high-degree melting of a mantle plume head. Boninite-like, low-Ti basement rocks at Manihiki, however, imply a more ...

What has been impossible has now been shown to be possible -- an alloy between two incompatible elements. What has been impossible has now been shown to be possible – an alloy between two incompatible ...

Apatite [formula: Ca5(PO4)3(F, Cl, OH)] is a mineral we should all be familiar with—our teeth are made of the OH-endmember apatite! For geologists, apatite is a well-known mineral because it commonly ...

The magmatic layers of the oceanic crust are created at constructive plate margins by partial melting of the mantle as it wells up. The chemistry of ocean floor basalts, the most accessible product of ...

This is a preview. Log in through your library . Abstract Quartz-monzodiorite is generally considered to represent the parent magma of high-Mg quartz-monzodiorite plutonic suites; thus such suites are ...

What is the chemical composition of the Earth's interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth's deep interior ...

June 26 (UPI) --New research suggests roughly 5 to 6 percent of the Earth's mantle is made up of recycled crust. The discovery, detailed Friday in the journal Science Advances, suggests Earth has been ...

Geochemists have investigated the volcanic rocks that build up the Portuguese island group of the Azores in order to gather new information about the compositional evolution of the Earth's interior.
