“Central uplifts are desirable targets for learning about impact conditions,” says Aaron Cavosie, an author of a study describing the discovery. “They bring profoundly damaged rocks closer to the surface, and in some instances, are associated with exploration targets. Finding reidite at Woodleigh was quite a surprise as it is much rarer than diamonds or gold, though unfortunately not as valuable.”
Along with the reidite, the team found formations called deformation twins. These features are only created when zircon grains are shocked in an impact, and their presence at Woodleigh backs up the idea that it’s larger than thought.
The research was published in the journal Geology.
