When the eruption occurs, zircons are released in the ash and lava, which then become rocks like rhyolite. Geologists hunt for these particular sorts of rock so far the volcanic eruption by which the rock fashioned. There are several different strategies for estimating ages utilizing half-lives, Macdougall explains. For isotopes with relatively rapid decay rates, researchers decide the proportion of a radioactive isotope relative to different atoms of the same element and examine it with how a lot of that isotope a contemporary pattern could be expected to have. With that data, along with the known half-life, it’s possible to estimate the age of the unique pattern.
