40 Facts About Reidite

What is Reidite?

Reidite is a rare mineral that forms under extreme pressure. It’s a high-pressure polymorph of zircon, meaning it has the same chemical composition but a different crystal structure. This mineral is fascinating due to its unique formation conditions and its implications for understanding geological processes.

1. Reidite was first discovered in 1969 by mineralogist Alan Reid.
2. It forms only under extreme pressure, typically found in meteorite impact sites.
3. The mineral is a high-pressure polymorph of zircon, sharing the same chemical formula (ZrSiO4).
4. Reidite has a tetragonal crystal structure, different from zircon’s tetragonal structure.
5. It is extremely rare, with only a few known occurrences worldwide.

Formation and Occurrence

Reidite’s formation is closely linked to high-pressure environments, such as those created by meteorite impacts. This makes it a valuable indicator of such events in geological history.

6. Reidite forms at pressures above 30 gigapascals (GPa).
7. It is often found in shock-metamorphosed rocks, which are rocks altered by the intense pressure of meteorite impacts.
8. The presence of reidite in a rock sample can confirm a past meteorite impact.
9. Reidite has been discovered in impact craters in the United States, Germany, and Australia.
10. It can also form during high-pressure experiments in laboratories.

Physical and Chemical Properties

Understanding the physical and chemical properties of reidite helps scientists learn more about the conditions under which it forms and its potential applications.

11. Reidite is denser than zircon, with a density of about 4.7 grams per cubic centimeter.
12. It has a higher refractive index than zircon, making it more optically distinct.
13. The mineral is typically colorless or pale in thin sections.
14. Reidite is stable at high pressures but reverts to zircon at lower pressures.
15. It can be identified using techniques like X-ray diffraction and Raman spectroscopy.
