Fig. Narrowing down the ages of those crystal inclusions (known as neoblasts) could reveal the date of the impact itself. It's possible, then, that the meteor slammed into a vast ice sheet instead of the desert that stands there today. Uranium is steadily converted to lead at a known pace, but when these crystals are shocked and heated up, they are suddenly rid of all lead, re-setting the 'isotopic clock'. A shocked zircon crystal that was used to date the Yarrabubba crater suggests that the impact occurred around the same time as Earths global deep freeze..
