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.. This makes some rocks in the centre of impacts vaporise, while others just melt at high temperature, often over 2,000 degrees C (3,600 F). Aaron J.

The scientists then used a high-tech scanning process known as Sensitive High Resolution Ion Micro Probe (SHRIMP) to search for microscopic grains that contain uranium inside them. Studies have found multiple periods in Earths history in which glacial deposits occur in rocks of the same age across many continents.
