Those crystals allowed Millot and colleagues to conduct the first laser-driven shock compression study of stishovite
using ultrafast optical pyrometry and velocimetry at the Omega Laser Facility at the University of Rochester's Laboratory for Laser Energetics.

John McHone and his colleagues at Arizona State University in Tempe report in the March 3 SCIENCE that they have detected a mineral called stishovite in samples collected from the K-T boundary at Raton, N.
The researchers detected the minute amounts of stishovite through two techniques, nuclear magnetic resonance and X-ray diffraction.
The important thing about stishovite is that it breaks down when heated.
A bit of stishovite found at a site where scientists are trying to prove that an asteroid once smacked into the earth would do wonders for their case.
With this method, the researchers clearly detected stishovite in a sandstone rock from a crater in Arizona.
He also says that no stishovite was detected in a K/T sample, but it may have been destroyed by the present preparation method.
