Defining magmatic differentiation as the process responsible for changing magma composition is not straightforward. In the past, numerous theories have been proposed for explaining variations in magma ...

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 ...

Chemical clues to formation The initial results from the model showed that under the reducing conditions of early Earth, the element niobium would become siderophilic, or attracted to metal, sinking ...

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 ...

Geologists have made certain assumptions about how the crust making up our planet's earliest surface formed, but a new study ...

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

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 ...
