Experiments show that too much lead (more than 5%) causes partial melting and glass formation above 1000 C.

This water is just warm enough to cause significant melting at the bottom of the ice shelves.

The shock waves caused momentary melting of these ice beds.

They are suggested to be hot, causing large-volume melting, and to be fixed in space.

The late 1970s saw the destruction of many early Kennedy half dollars, as high silver prices caused extensive melting for the metal content.

The late heavy bombardment, whether it was the end of accretion or a separate event, is even less likely to cause widespread melting.

Large impacts caused local melting of the iron rich H chondrite surface.

And that water is about 2.7 degrees Fahrenheit warmer than it was only a decade ago, causing further melting.

Increasing the pressure drives the water into the higher density phase, which causes melting.

However, if the water composition of wadsleyite surpasses a 0.1-0.2 wt% amount, it could cause partial melting.
