The heat from a volcanic eruption releases all the argon from the molten rock and disperses it into the atmosphere.

Argon then starts to re-accumulate at a constant rate in the newly formed rock that is created after the eruption.

The level of nitrogen gradually reduces as the bone decays.

It is initially formed in the molten rock that lies beneath the Earth’s crust.The number of tracks increases over time at a rate that depends on the uranium content.It is possible to calculate the age of a sample by measuring the uranium content and the density of the fission tracks.This problem is now reduced by the careful collection of samples, rigorous crosschecking and the use of newer techniques that can date minute samples.Volcanic rocks – such as tuff and basalt – can be used in dating because they are formed at a particular moment in time, during an eruption.
