The skeleton of massive reef-building corals records the past tropical-temperate environmental conditions in which they grow. Coral skeletal luminescence bands and/or lines irradiated by ultraviolet light have been used to investigate past precipitation and river flood. In pioneer studies involving investigation of coral luminescent bands, it was found that the distinct luminescent bands observed in coral annual bands were formed by coral aragonite, organic matters in coral skeletons especially humic substances, skeletal structure such as skeletal cavities. The results of several studies confirm that coral luminescent bands are derived from humic substances because the luminescent bands were more abundant in areas where humic substances were concentrated than in other skeletal parts and seawater. On the other hand, several studies have been shown that the coral luminescent bands correspond to the skeletal parts of low skeletal density. However, the cause of the formation of the luminescent bands still remains a controversial topic. Elucidating coral luminescent bands is essential for establishing reliable environmental proxies for reconstructing past precipitation and river flood events.
