When the eruption happens, zircons are launched in the ash and lava, which then become rocks like rhyolite. Geologists hunt for these specific sorts of rock so far the volcanic eruption during which the rock shaped. There are several different methods for estimating ages utilizing half-lives, Macdougall explains. For isotopes with relatively fast decay rates, researchers determine the proportion of a radioactive isotope relative to other atoms of the same component and compare it with how much of that isotope a fresh pattern could be anticipated to have. With that information, along with the known half-life, it’s potential to estimate the age of the original sample.
