All dating methods today can be grouped into one of two categories: .
The former gives a numeric age (for example, this artefact is 5000 years old); the latter provides a date based on relationships to other elements (for example, this geological layer formed before this other one).
Any scientific discipline for which chronology is important may utilize these dating methods.
They may tell us many things including age, but also its place in a sequence of processes.
As lead isotope decay at a standard and slow rate, it's able to provide fairly accurate date ranges which it measures in the millions of years.
For further details, see uranium-lead dating section below.
Amino acid dating: This relatively new form of absolute dating is useful in archaeology, anthropology, paleobiology, molecular biology and anything else that may study organic substances to pinpoint an actual date or define a date range.
But they can also show human intervention such as when woodland was cleared to make way for agriculture (6).Lead-lead dating: Another method that studies the chemical attributes of rocks, it's largely been superseded by uranium-lead dating in geological studies.However, it remains useful to astronomers and astrophysicists in dating meteorites and other extraterrestrial deposits on Earth.Most are multidisciplinary, but some are limited, due to their nature, to a single discipline.No system is completely failsafe and no method completely correct, but with the right application, they can and have aided researchers piece together the past and solve some of their discipline's most complex problems.
