magma

Proposed explanations have included differences in how the Moon's original magma ocean circulated, a massive collision, heating caused by gravitational tides, and uneven development of the lunar crust.

Earth had what's known as a magma ocean stage with an entirely liquid surface.

These rocks can form when magma cools underground or when volcanic material solidifies at the surface.

The researchers concluded that this olivine-rich unit originally formed inside a mass of magma deep beneath the Martian surface.

Beneath the surface is a magma chamber that is about forty-five miles across–roughly the same dimensions as the park–and about eight miles thick at its thickest point.

The main process enriching these magmas with gold appears to be high-degree, multi-stage melting of a water-rich and oxidized mantle.

The team took this as evidence that these two sets of zircons formed from shallow magmas that interacted with freshwater.

To be certain, the researchers performed tens of thousands of computer simulations of zircons forming from magmas mixed with seawater, rainwater, or some combination of both.

The very great viscosity of acid magmas prevents their molecules, especially when cooling takes place suddenly, from arranging themselves to form discrete crystals, and is the principal cause of the production of felsitic ground-masses.
