Potassium argon and argon argon dating techniques are used on
There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
It was the case of an 18th-century sloop whose excavation was led in South Carolina (United States) in 1992.
Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity.
It is commonly assumed that if the remains or elements to be dated are older than the human species, the disciplines which study them are sciences such geology or paleontology, among some others.
This usually requires what is commonly known as a "dating method".
Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history, archaeology, geology, paleontology, astronomy and even forensic science, since in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred.
Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
