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 ...

“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 ...

In one scenario, the melt occurs and is retained beneath the crust as a result of the mantle upwelling and decompression melting that forms the newly emerging plate material. Another theory proposes that the melt is generated in small amounts ...

... asthenosphere is "hot and somewhat buoyant, and if there's a topographic gradient along the asthenosphere's upper surface, as there is under the Colorado Plateau, the asthenosphere will flow with it and undergo a small amount of decompression ...

“This is because the reduction in the ice load reduced the pressure in the mantle, leading to decompression melting there. Since the late 19th Century the ice caps in Iceland have been shrinking yet further, due to changing climate. This will lead to ...

“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 ...

His theory suggests that Mount Etna is not directly the result of tectonic plate boundary activity, but that it resulted from decompression melting of upper mantle material flowing around the nearby edge of the Ionian slab that is slowly sinking into ...

In the first stage, a basin-forming impact event causes large degrees of instantaneous mantle melting, followed by a second stage involving adiabatic decompression melting and extrusion of mare basalts into the newly created impact basin5. Our findings ...
