Read More Understanding rates and variability of Earth-surface processes is vital to assessing natural hazards, landscape response to climate change and addressing concerns related to food security and water supply.
Surface processes affect the critical zone, where life interacts with the land surface, and are archived in sediment records.
Luminescence dating methods are specifically used in geology and archaeology.
In more extensive dating models the usability of method grows when separate luminescence dating results can be added for example with radiocarbon results and thereby grow up the knowledge behind the models.
Erosion histories can be inferred by translating rock cooling rates into an erosion rate using knowledge of the Earth’s thermal field.
In this article, we use examples of luminescence thermochronometry applied to the Himalaya mountains, the New Zealand Alps and the Japanese Alps to infer (and link together) wider aspects of regional erosion, climate and tectonic activity.
This total dose can be used to the age determination when we measure the dose rate of radiation that has given that dose.
Age (the time from the latest emptying of traps) can be found out by dividing the total dose with dose rate.
Thermoluminescence dating was applied originally to heated pottery and burnt flint, and optical dating was developed subsequently to estimate the depositional age of sun-bleached sediments associated with artefacts and fossils. [ Datation par luminescence stimulée optiquement : quelle signification en cas de blanchiment incomplet des sédiments fluviatiles ? In: Quaternaire, 15, (1-2), 2004, p 143-157 OPTICALLY STIMULATED LUMINESCENCE DATING: HOW SIGNIFICANT IS INCOMPLETE LIGHT EXPOSURE IN FLUVIAL ENVIRONMENTS? Optically stimulated luminescence dating: how significant is incomplete light exposure in fluvial environments? Luminescence dating provides an age estimate for sediment deposition and can provide dates to calculate rates and recurrence intervals of natural hazards and Earth-surface processes.This method has produced robust age estimates from a wide range of terrestrial, marine, tectonic, and archaeological settings.
The radiation dose rate from the grain’s local environment, which ideally should be homogeneous, is what is routinely measured for luminescence dating.
