Dendrochronology is a term used for the study of vegetation remains, old buildings, artifacts, furniture, art and musical instruments using the techniques of dendrochronology (tree-ring dating). It refers to dendrochronological research of wood from the past regardless of its current physical context (in or above the soil). This form of dating is the most accurate and precise absolute dating method available to archaeologists, as the last ring that grew is the first year the tree could have been incorporated into an archaeological structure.〔Feder K. Linking to the Past: A Brief Introduction to Archaeology. 2nd Ed. Oxford University Press. 2008〕 Tree-ring dating is useful in that it can contribute to "chronometric", "environmental", and "behavioral" archaeological research.〔Nash S. E. Archaeological Tree-Ring Dating at the Millennium. ''Journal of Archaeological Research'', Vol. 10, No. 3 (September 2002), pp. 243-275〕 The utility of tree-ring dating in an environmental sense is the most applicable of the three in today's world. Tree rings can be used to "reconstruct numerous environmental variables" such as "temperature", "precipitation", "stream flow", "drought society", "fire frequency and intensity", "insect infestation", "atmospheric circulation patterns", among others.〔 ==History== Tree ring laboratory scientists from Columbia University were some of the first to apply tree-ring dating to the colonial period, specifically architectural timbers in the eastern United States. For agencies like the National Park Service and other historical societies, Dr. Jacoby and Cook began dating historic structures in the lower Hudson River Valley, New Jersey and Eastern Pennsylvania. This was difficult at the time due to a lack of sufficiently long master dating chronology and access to suitable structures. Not until 1998 was a Boston area master dating chronology developed. Today, the effectiveness of tree ring laboratory archaeological dating chronologies covers most of the area that was settled by the first European colonists. The numbers of these are in the hundreds and include historically significant structures such as Independence Hall and the Tuckahoe estate. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dendroarchaeology」の詳細全文を読む スポンサード リンク
