OPTICAL DATING: A LUMINOUS PAST AND A VERY BRIGHT FUTURE
Most development of luminescence technique and application has focused on geological (unheated) sediments. Since the year 2000, there has been the introduction of several additional variants of TL and OSL dating procedures giving rise to new hybrids of the OSL dating “family” including thermal-transfer OSL, post infrared stimulated luminescence, near infra-red radio-fluorescence, and developments in violet light stimulated luminescence to sample deep traps in quartz. Each hybrid is suited to differing geological deposits, processes, and age ranges. Examples will be presented of basic concepts and applications to sediment or rock dating spanning the age range from <1 ka to ~900 ka using innovative instrumentation and new methodological procedures.
