Dendrochronology tree ring dating kit

Radiocarbon dating currently provides the best estimates, but are only accurate to within 200 to 300 years.

The two spikes, known as Miyake events, can be detected in the unusually high levels of radioactive carbon-14 in tree-rings that grew over that time period.

The sequence is created by overlaping the tree rings so a long series of rings can be seen.

When done correctly dendrochronology can be used by archaeologists to date the cutting of a tree to within a year. Dendrochronology can only be used effectively in places with distinct seasons because the change in season is what causes distinct tree rings to be produced.

Researchers from the University of Oxford, Michael Dee and Benjamin Pope, published their results today in Proceedings of the Royal Society A.
