It is the science of assigning calendar-year dates to the growth rings of trees, and Colorado figures prominently in its development and application in archaeology and other disciplines. Tree-ring dating provides scientists with three types of information:
Calibration is not only done before an analysis but also on analytical results as in the case of radiocarbon dating —an analytical method that identifies the age of a material that once formed part of the biosphere by determining its carbon content and tracing its age by its radioactive decay. Carbon is a naturally occurring isotope of the element carbon.
Dating of archaeological timbers. Dating of period buildings.
Ron Towner from the Laboratory of Tree-Ring Research at the University of Arizona explains the principles behind dendrochronology and why this dating method is valuable to archaeologists. Ron demonstrates how to accurately count tree-rings, and discusses the importance of patterns and master chronologies.
Dendrochronology or tree-ring dating is the scientific method of dating tree rings also called growth rings to the exact year they were formed in order to analyze atmospheric conditions during different periods in history. Dendrochronology is useful for determining the timing of events and rates of change in the environment most prominently climate and also in works of art and architecture, such as old panel paintings on wood, buildings, etc.
