Optical dating of potassium feldspar using far-red (λ>665nm) IRSL emissions: a comparative study using fluvial sediments from the Loire River, France

UV-blue emissions from feldspars have often proved to be unacceptable dosimeters for age estimation given the intrinsic problem of anomalous fading. The potential of exploiting the far-red (> 665nm) IRSL emissions from potassium feldspars as a means of avoiding the ...
