Luminescence Chronology and Climatic Records
The aim of this session is to bring together experts on luminescent dating (both OSL and autocalibration dating) with the experts on luminescence paleoclimatic records (in speleothems and corals) and in paleoclimatic applications of cathodoluminescence in order to discuss further development of luminescence techniques and their applications in geology, paleoclimatology, reconstruction of the past environments and global change. .
Speleothem luminescence (which is called paleoluminescence) provides high-resolution proxies of the paleotemperature, insolation, solar luminosity, glacial-interglacial cycles, past precipitation, surface plant communities, paleosoils and chemical pollution in the past. Some speleothems can even be used as natural climatic stations for obtaining of quantitative proxy records of the Holocene climate, with annual resolution. Monthly and better resolution is achieved in some records.
Speleothem luminescence may be used to determine the age of the speleothem itself and to date the record by autocalibration dating technique, which is one of the most precise speleothem dating methods for samples younger than 2000 years.
Optically stimulated luminescence (OSL) dating works well for dating of much older samples of other minerals (especially quartz). Its bases are similar to the thermal luminescence (TL) and ESR dating, but OSL dating works better on some samples. Thus different luminescence methods compliment each other, but they are developed in different scientific communities, which do not communicate together yet. This session will fill this gap, so it is expected to be very stimulating for the development of these new exciting fields of paleo- environmental research.
