Most of the silica in rhyolitic magma comes from this composition. Chemically, silica is a compound of silicon dioxide (SiO2). It is the opposite of fluidity to be viscous (in terms of resistance to ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs ...

The source for the isotopically-enriched Hawaiian magmas contains peridotites that experienced near-surface melting prior ...

They looked at the composition, structure, and history of rocks deep beneath the Earth's crust, alongside information gathered from active volcanoes, to understand how magma builds up and behaves ...

It’s long been thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in ...

Kimberlites are rather susceptible to alterations that modify their original composition. Even though this pipe appears fresh there has been some debate about whether the saltiness of the magma ...

The researchers used multiple methods to determine its composition and then compared ... it was covered by an ocean of magma. Chang'e-6 basaltic fragment. Credit: Beijing SHRIMP Center, Institute ...

Scientists have long known that volcanoes shaped the near side of the Moon, visible from Earth. However, very little was ...
