Here is another story about this discovery:

I want to know more about the meteorite, a carbonaceous chondrite with
shocked quartz. It sounds like a unique rock.

Thanks,

Peter

Oddball 'Crystal' Survived Crash to Earth Inside Meteorite

A bizarre crystal-like mineral recently found in a meteorite that crashed to
Earth perhaps 15,000 years ago adds more support for the idea that the
fragile structure can survive in nature. But how it formed at the beginnings
of the solar system is still a mystery.

The newfound mineral is called a "quasicrystal" because it resembles a
crystal, but the atoms are not arranged as regularly as they are in real
crystals. The quasicrystal hitched a ride to Earth on a meteorite that
zipped from space through Earth's atmosphere and crashed to the ground.
That process is generally a violent one that heats up the insides of rocks,
making the delicate quasicrystal's survival a surprise.

"The difference between crystals and quasicrystals can be visualized by
imagining a tiled floor," said according to a statement by Princeton
University in a press release. "Tiles that are six-sided hexagons can fit
neatly against each other to cover the entire floor. But five-sided
pentagons or 10-sided decagons laid next to each will result in gaps between
tiles."
