Ikeya dated a method has been applied to about. The surface of obsidian has a strong affinity for water as is shown by the fact that the vapour pressure of the absorption continues until the surface is saturated with a layer of water molecules. In the disintegration process the Carbon returns to nitrogen emitting a beta particle in the process. We identified several sources of uncertainty that may directly impact the accuracy of the age result.

Its usefulness is limited to distinguishing modern from prehistoric and prehistoric from Pleistocene like that. Often, the tree-ring analysis from a site can give strong clues about the length of occupation, certain periods of building or repair activities at the site. More details Article metrics.
