Global warming alarmists should hold protests against meteorites …
An innocuous crater in Yarrabubba, Western Australia has been identified as the oldest known extraterrestrial impact site on Earth, with researchers calculating that the natural structure dates back a whopping 2.229 billion years.
Researchers from Curtin University tested minerals found in rocks at the site. The zircon and monazite crystals in the rocks themselves contain tiny amounts of uranium, and by measuring the uranium’s very specifically-timed decay into lead, the team was able to calculate exactly how old the crater is.
The 70 kilometer (43 miles) diameter crater was actually discovered in the outback in 1979, with scientists mapping the area’s magnetic field to determine the exact extent of the weather-worn structure. The recent mineral analysis means the site is now believed to be at least 200 million years older than the next oldest alien impact – the Vredefort dome in South Africa.
