Decompression partial melting

This video summarizes the decompression partial melting process beneath oceanic-oceanic divergent boundaries.

Magma evolution rise from mantle

This video summarizes how rising magma from the mantle interacts with the lithosphere, thus creating a range in magmatic compositions.

Microchemical Disequilibrium Fractional Decompression Melting of Mantle Peridotite

Typical result of a two-dimensional numerical model of multi-phase coarsening, diffusive trace element partitioning (La, Sm, Yb), and near-fractional melting.

So, underneath mid-ocean ridges (and at hotspots like Hawaii), the mantle is upwelling, causing decompression melting to occur. Let's review: Under normal conditions, mantle rock like peridotite shouldn't melt in the Earth's upper mantle — it is just ...

Due to decompression melting, molten magma rose through this fault. But rather than reaching the surface, the magma spread out between the older layers of sandstone. This type of geologic structure is known as a sill. After the diabase of the Palisade ...

“If Basin and Range extension were to occur here, it could result in an eruption, because when the crust is stretched and pressure are released, decompression melting can occur.” Craters of the Moon encompasses more than 1,100 square miles, roughly the ...

England and Katz models suggest that in the mantle wedge, there is a very restricted zone where this type of melting - decompression melting like we find at the midocean ridges - is allowed and it is this zone that dictates the location of the arc (see ...

“At the end of the last ice age, the rate of eruption in Iceland was some 30 times higher than historic rates. “This is because the reduction in the ice load reduced the pressure in the mantle, leading to decompression melting there. “Since the late ...
