Luminescence bleaching
-
There is growing interest in rock surface burial and exposure luminescence dating for use in Quaternary science and in archaeology. Such methods have enormous potential both in increasing the range of sedimentary contexts that can be dated, and improving the accuracy and the precision of dating within those contexts.

Using luminescence to date the burial and exposure ages of rock surfaces has been a revolutionary new geochronological approach developed and refined over the past decade. Rock surface exposure dating is based on the principle that the depth to which the luminescence signal is bleached into a rock surface is dependent on the duration of that rock surface’s exposure to sunlight.

Optically stimulated luminescence (OSL) depth profiling utilizes an OSL-at-depth signal to extrapolate an exposure age from rock surfaces. Exposure ages are commonly obtained by fitting the forms of luminescence depth profiles, which depend on parameter estimates of light attenuation and defined rates of luminescence bleaching.
