Testing the upper limit of infrared radiofluorescence (IR-RF) dating in nature is a critical step in developing our understanding of the signal and its potential. The Luochuan loess-palaeosol sequence on the Chinese Loess Plateau is a well-documented sequence spanning over Ma, that has served as a proving ground for many trapped charge dating techniques, for example: feldspar post-infrared infrared stimulated luminescence (pIRIR), quartz electron spin resonance (ESR), and quartz violet stimulated luminescence (VSL). |
