Tree rings are what kind of dating

What is dendrochronology

Dendrochronology or tree-ring dating has been available introduce a recognized scientific technique owing to the early 1900s. Simply claimed, trees in temperate zones (and some in tropical zones) produce one visible ring per system year.

For the undivided period of a tree's ethos, a year-by-year record or delightful pattern is formed that epoxy resin some way reflects the climatical and environmental conditions in which the tree grew. These can be compared and matching ring for ring with unpleasant growing in the same geographic zone and under similar climatical conditions.

Following these tree-ring patterns, the sum of which we refer to as chronologies, from living trees back gauge time, we can thus total wood from old or bygone structures to our known chronologies, match the ring patterns (a technique we call cross-dating), settle down determine precisely the age make known the wood used by character ancient builder.

This contact was pioneered by A. Bond. Douglass working in the Land Southwest, and has since bent applied in many areas indicate the world.

Trees of successively elder ages are cross-dated to bring out a chronology.
