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 ...

Recent findings from the lunar samples brought back by China's Chang'e-5 mission are shedding new light on the Moon's history. In December 2020, the return capsule of this mission landed in Inner ...

He also discovered several new types of minerals, such as coesite and stishovite, which are formed by high-pressure shock waves from impacts. He co-discovered Comet Shoemaker-Levy 9 with his wife ...

Fortunately, one silica fragment obtained in the CE-5 sample was found to possess both stishovite and seifertite, silica polymorphs that are unique because they should only be able to coexist under ...

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 quartz ...

This process is characterized by a rapid change in temperature and pressure, leading to the formation of high-pressure minerals like stishovite and seifertite. These minerals, though chemically ...

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 ...

These conditions alter the structure of the moondust, leading to the formation of quartz-like silica minerals like stishovite and seifertite. "Although the lunar surface is covered by tens of ...

Specifically, the silica polymorphs in question were seifertite and stishovite, which are chemically identical to quartz. At first glance this was puzzling, since high-pressure minerals like ...

The returned Chang'e-5 samples also contain a mix of previously known silica minerals, most notably seifertite and stishovite. Scientists think those two minerals were likely deposited by the ...
