Optically Stimulated Luminescence Dating (Instrument Design for Mars Applications)
Introduction: To examine the geological and climatic history on Mars, we investigate an instrument design for robotic, in-situ, Optically Stimulated Luminescence dating (OSL). In this paper, we discuss the basic concepts of OSL, its benefits, and how this technique can be utilized on Mars. Also presented are the vital electronics needed for an instrument design and some of their basic operation...
متن کاملPrecision and Accuracy in the Optically Stimulated Luminescence Dating of Sedimentary Quartz: a Status Review
Optically stimulated luminescence (OSL) dating of light-exposed sediments is used increasingly as a mean of establishing a sediment deposition chronology in a wide variety of late Quaternary studies. There has been considerable technological development in the last few years – in instrumentation, in the preferred mineral, and in various measurement protocols. New approaches to the latter, espec...
متن کاملOptically stimulated luminescence in synthetic quartz
Optically stiniulated luminescence (OSL). has been studied in synthetic quartz crystals. which had previously been exposed to Jtor X-irradiations. The main emission hands appeared at 380 and -~440 nm. The excitation spectra of these emission bands were now measured and showed both a maximum at 330nm. This maximum coincides with an excitation maximum of the phototransferred thermoluminescence (P...
متن کاملUse of luminescence dating in archaeology
With improvements in methodology and instrumentation, luminescence dating is becoming a much more useful chronometric tool in archaeology. Procedures for dating ceramics are relatively routine and their accuracy has been demonstrated in a number of studies. Research is aimed at applying ceramic dating in situations where other methods lack the direct dating ability of luminescence to resolve ch...
متن کاملProgress towards robotic in-situ dating of martian sediments using optically stimulated luminescence
Recent exploratory efforts to reveal the evolution and the climatic history of Mars have shown that the planet is still active. The surface of Mars has been, and continues to be, shaped by fluvial, eolian and glacial processes. The timeframe of these events is, however, poorly established. We describe efforts and challenges to adapt optically stimulated luminescence (OSL) dating for robotic in-...
