CATEGORY: technique DEFINITION: A diagram in the form of a schematized tree with many branching lines at one end and uniting into a single trunk at the other -- used to record the analysis of tree-ring widths for a sample(s).

It is then compared to a master chronology in dendrochronology studies.

technique for measuring time intervals and dating events and environmental changes by reading and dating the pattern (number and condition) of annual rings formed in the trunks of trees.

The results are compared to an established tree-ring sequence for a particular region with consideration to annual fluctuations in rainfall which result in variations in the size of the rings laid down by trees on the outside of their trunks.

In Ireland, oak preserved in bogs has produced a SYNONYMS OR RELATED TERMS: absolute dating; chronometry CATEGORY: technique DEFINITION: Any technique of dating that relies on chronological measurement such as calendars, radiocarbon dates, etc.The methods have varying applications, accuracy, range, and cost.Many new techniques are being developed and tested.These variations, given favorable conditions, form a consistent pattern; and sections or cores taken from beams in ruins have been matched to provide a long chronology over large areas.The method is based on the principle that trees add a growth ring for each year of their lives, and that variations in climatic conditions will affect the width of these rings on suitable trees.
