  1. Ḋ is the dose rate. De is the equivalent dose. D0 is the characteristic saturation dose of the electron trap. n/N is the signal saturation level, which is the ratio of the measured TL signal intensity and the maximum TL signal intensity at saturation. TC is the effective closure temperature calculated from the cooling rate, the surface temperature and the apparent TL age. Cooling rates of the fault clasts have not been modeled as their TL ages indicate a signal resetting event at ~2.5 Ma, rather than cooling ages. Errors for all values are 1σ.
  2. aThe 100–200 µm grain size fraction was used for all samples. However, a grain size fraction of 63–100 µm was also measured for sample LUM4525, to make comparison with the 100–200 µm grain size fraction.
