A Review on Application of Super-Long Tree Ring Chronologies in Global Change Fields:Taking ~(14)C calibration, archaeological dating and catastrophic events as examples
Dendrochronology has been developed rapidly during the past decades.There are a large number of super-long (>1 000 years)tree-ring chronologies produced in different parts of the world.The main aim of this article is to introduce and review some important applications of long tree-ring chronologies in the following aspects.Firstly,in order to date the archeology sites precisely,the ~(14)C age should be converted to the calendar age with the help of the correct'~(14)C calibration curve derived by the long tree-ring chronology.Secondly, long tree-ring chronologies are widely used in dating the ancient architectures and coffins.Finally, the paper introduced the application of long tree-ring chronologies in dating geological catastrophic events, such as dates of large earthquakes and volcanic eruptions.However,there are still many unavoidable problems needed to be solved in the applications of long-term tree ring chronologies.For instance,the longest tree-ring chronology spans only 12 410 years in the whole ~(14)C calibration curve and is necessary to extend the calibration curve.Moreover,there are no sufficient wooden samples when determining the exact age of historical artifacts.Therefore,we should extend super-long tree ring chronologies and develop stable carbon and oxygen isotope series if we want to make more contributions to the work of tree ring application in such scientific fields.
