Lava carbon dating


Generally, of artefacts, only wooden artefacts can be dated directly - either by carbon dating or dendrochronology . Other kinds of artefacts can only be dated indirectly, usually from the context of their finds. For example, it may be possible to find arrowheads together with dateable pollen, or tied to wooden arrowstalks, or next to people of a distinct culture whose appearance and disappearance times are known.

First, scientists have observed that radioactive isotope (radioisotope) decay rates do fluctuate, including Th-228, Rn-22, and Si-32. Although these particular isotopes are not used to date rocks, they illustrate that radioisotope decay (radiodecay) is not always constant. 1
