Look up this process and evaluate the mechanism for how it works.

It essentially allows dating of samples based on when they were last exposed to sunlight.


To resolve this, radiocarbon dating of these samples from Waun Mawn was conducted in conjunction with optically stimulated luminescence (OSL)dating of sediment from within the packing deposits that were contemporaneous with the monoliths’ erection, and from filled-in sockets (from after the monoliths’ removal). OSL dating determines the burial age of sediments, with the dating signals being reset by light exposure immediately prior to deposition (Smedley2018). 1
