“…Previously, optically stimulated luminescence (OSL) has been used successfully in dating depositions of Tall structures in the Jordan Valley and identifying post-depositional reworking in the layers (al Khasawneh et al, 2011(al Khasawneh et al, , 2017(al Khasawneh et al, , 2019(al Khasawneh et al, , 2020.
