Dendrochronology dating techniques Free xxx 1to1 camchat
There are two main categories of dating methods in archaeology: indirect or relative dating and absolute dating.
Relative dating includes methods that rely on the analysis of comparative data or the context (eg, geological, regional, cultural) in which the object one wishes to date is found.
By cross-linking core samples from living and dead trees, a master sequence of annual tree-ring widths can be compiled.
Another problem is that there may be gaps in the sequences of available timber, so that the chronology 'floats', or is not tied in to a calendrical date or living trees: it can only be used for .
Also, the tree-ring key can only go back a certain distance into the past, since the availability of sufficient amounts of timber to construct a sequence obviously decreases.
Fortunately, there are other methods available to researchers.
All trees of the same species in an area usually have roughly the same pattern of growth.
