Geologists https://cupidcritique.com/be2-review/ hunt for these explicit types of rock to date the volcanic eruption during which the rock fashioned. There are a quantity of different strategies for estimating ages using half-lives, Macdougall explains. For isotopes with comparatively rapid decay rates, researchers determine the proportion of a radioactive isotope relative to other atoms of the same element and examine it with how a lot of that isotope a contemporary pattern can be anticipated to have. With that data, together with the known half-life, it’s potential to estimate the age of the original pattern.
