Abstract: 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 ¹⁴C age should be converted to the calendar age with the help of the correct' ¹⁴C 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 ¹⁴C 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.

Key words: long tree ring chronology, radiocarbon calibration, archaeological dating, catastrophic events
