Dendrochronology: Because most woods build a ring of brand new wooden annually, archaeologists utilize the modifications in cross-sections of timber to make timelines.

Thermoluminescence: ideal for determining the age of pottery or ceramics, you can use it up to now materials that contain crystalline nutrients to a particular heating celebration in earlier times (like whenever the product was created).

Fission-track relationships: A technique that find ages of various vitamins and cups based on the tracks of damage done-by the natural fission of uranium-238, more numerous isotope of uranium.

Potassium-argon (K-Ar) and Argon-argon (Ar-Ar): measure the proportion of argon petrol in igneous eruptive rock to calculate the length of time has elapsed ever since the rock cooled off and solidified.
