Dendrochronology is the study of data from tree ring growth. Archaeology - for the purpose of dating materials and artefacts made from wood. . Until the s , it was notoriously difficult to date waterlogged archaeological sites, which was. This new chronology could aid further dating of wood from archaeological sites and historical structures, and establish an initial data set that could eventually. 69–78 RESEARCH REPORT DENDROCHRONOLOGICAL DATING OF This project demonstrates the feasibility of dating wood extracted from sites from the.

The depth feature that is currently thought to be a log sleeper at which the two features became apparent is also sill support a pad on which the large bottom quite different Table 5.

The dendrochronological date for the than the cypress posthole, and its base was 25 cm post, combined with the stratigraphically intrusive higher than the base of the cypress post. The position of the posthole, suggest that the building different elevations, as well as the different wood represented by the sleeper sill was destroyed before varieties, suggest two distinct building episodes.

A new layer of wood is added in each growing season, thickening the stem, existing branches and roots, to form a growth ring. Horizontal cross sections cut through the trunk of a tree can reveal growth rings, also referred to as tree rings or annual rings. Growth rings result from new growth in the vascular cambiuma layer of cells near the bark that botanists classify as a lateral meristem ; this growth in diameter is known as secondary growth.

Visible rings result from the change in growth speed through the seasons of the year; thus, critical for the title method, one ring generally marks the passage of one year in the life of the tree. Removal of the bark of the tree in a particular area may cause deformation of the rings as the plant overgrows the scar.

The rings are more visible in trees which have grown in temperate zoneswhere the seasons differ more markedly. The inner portion of a growth ring forms early in the growing season, when growth is comparatively rapid hence the wood is less dense and is known as "early wood" or "spring wood", or "late-spring wood" [17] ; the outer portion is the "late wood" sometimes termed "summer wood", often being produced in the summer, though sometimes in the autumn and is denser.

Many trees in temperate zones produce one growth-ring each year, with the newest adjacent to the bark. Hence, for the entire period of a tree's life, a year-by-year record or ring pattern builds up that reflects the age of the tree and the climatic conditions in which the tree grew.
