The content of both fluorine and silicon in bone, as well as the Ca: (PO) molar ratio, are time-dependent, which means that these parameters seem to be suitable for dating purposes.

Methods and improvements are proposed in order to make chemical analysis and chemical dating of bone as reliable as possible.

In addition, every spectrometer requires a unique correction for every major element in monazite.

An analytical protocol is presented that incorporates these results.

The results indicate that silicon is gradually incorporated into the bone mineral in a similar manner to fluorine.

It is suggested that silicate replaces phosphate in the bone apatite crystals.

This usually requires what is commonly known as a "dating method".

Sixty-one of these bones were also analysed for 13 other major and minor elements.But this method is also useful in many other disciplines.Historians, for example, know that Shakespeare's play Henry V was not written before 1587 because Shakespeare's primary source for writing his play was the second edition of Raphael Holinshed's Chronicles, not published until 1587.Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was left in a stratum.
