The OSL measurements were undertaken at the Luminescence Dating Laboratory at the University of California, Riverside. The in situ water content (mass of moisture/dry mass; Aitken, 1998) was determined using sub-samples by drying them in an oven at 50°C. The sample for dating was dry sieved to obtain a 90-125 µm or a 125-180 µm particle size

Optical Stimulated Luminescence Dating Study of Eolianite

A new method of dating potassium feldspar grains from aeolian sands is demonstrated. A luminescence signal is measured whilst the grains are stimulated in the near infrared at 880 nm. A surface sand sample gave an age of 40 ± 15 years, showing that this method is able to provide ages for very young samples. Since the measurement of an infrared stimulated luminescence (IRSL) signal can take
