光学测年法被应用于德国南部铁器时代定居点的自然和人为淤泥。自然沉积物的年代被准确测定，可以研究人类对景观的影响。研究的人为沉积物是地窖和沟渠的填充物。土壤侵蚀产生的沉积物再次被证明可以使用红外光学受激发光进行数据测定。然而，当沉积物由漂白和未漂白颗粒的混合物组成时，细粒沉积物的光学测年就受到限制。这在来自地窖填充物的已知年龄的沉积物上得到了证明。使用 560 nm 发射和部分漂白方法时取得了改进。实验证据表明，只有在所有谷物都未充分漂白到相同程度的情况下，DE 与光泽时间图才显示漂白不充分。
Optical dating was applied to natural and anthropogenic silts at an Iron Age settlement in southern Germany. The natural sediments were dated accurately and allowed study of the human impact on the landscape. The studied anthropogenic sediments were infills of cellars and ditches. Again, deposits derived from soil erosion proved to be datable using infrared-optically stimulated luminescence. However, optical dating of fine grained sediments was at its limits when sediments consisted of a mixture of bleached and unbleached grains. This is shown on sediments of known age originating from cellar infills. Improvements were obtained when using the 560 nm emission and a partial bleach approach. Experimental evidence shows that the D E versus shine-time plot discloses insufficient bleaching only in cases in which all grains are insufficiently bleached to the same degree.
