Then, within the next billionth of a second, the dense silica crystallises into a very rare mineral called stishovite. The results are particularly exciting because stishovite is exactly the ...

Change of lattice volume during heating to 1300ºC at 23 GPa. Hydrous stishovite crystalized at 500ºC showed large lattice volume, whereas the lattice volume after dehydration by subsequent ...

The results show that rutile-type silica (stishovite), which is widely stable in the upper part of the lower mantle, undergoes a phase transition to a CaCl 2-type phase, when it contains water and ...

The researchers used lab-based mimicry to study the mineral stishovite, which is a high-pressure form of quartz, when it's with water under high pressure and temperature conditions. We already ...

This temperature and pressure change occurs rapidly and has distinctive features, including the formation of silica polymorphs like stishovite and seifertite, which are chemically identical to ...

In a new paper, published this week in the journal PNAS, scientists have described for the first time the remarkable water-carrying abilities of the mineral stishovite, a unique form of quartz.

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen ...
