chick dating - Carbon 14 dating range


This does not mean that we have a precise year of 3780BC, it means we then need to calibrate through other methods that will show us how atmospheric concentrations of the C isotope has changed - most typically through the dendrochronology records (tree ring data) (10).

Typically, a Master's Degree in chemistry is required because of the extensive lab work.

Increasingly though, students are learning about the principles of radiocarbon dates in archaeology, palaeontology and climate science degrees and can combine cross-disciplinary studies.

This allows researchers to account for variation by comparing the known records of C levels in the tree record, looking for a tree record that has the same proportion of radiocarbon.

The overlapping nature of the tree records means this is the most accurate record we have.

It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.
