Short summary
We apply luminescence dating of feldspars to establish a geochronological framework for the sequence of accretionary hillslope deposition at Jojosi, which contains important archaeological artefacts. We test and evaluate four different dose models and their applicability to single-grain and multi-grain data sets containing up to 67 % saturated grains. Our results constrain erosional and depositional processes from 100–700 ka and human occupation of the area in early MIS 5 and late MIS 6.
