And yet they just now are pointing out assumptions that have been made by other geologists for decades.
This leads to the question: what assumptions are geologists making about their own preferred methods?
That’s just over half a percent error in something that is supposedly multiple billions of years old.
Of course, that error estimate is complete nonsense.
That assumption relies on theories of solar system formation.
” The photo shows a zircon crystal with two spots differing by 20 million years, within the same rock! Geologists from the Queensland University of Technology (QUT) offer these warnings about dating zircons: cautions against misinterpretation of zircons even in the title: “Use and abuse of zircon-based thermometers: A critical review and a recommended approach to identify antecrystic zircons.” Antecrystic zircons are units of rock within a zircon that became incorporated before the zircon crystallized.
