Through various arrangements of pre-heat and cut-heat temperatures in the equivalent-dose estimation of Holocene loess using a Double-SAR dating protocol

the paper estimated the equivalent-doses from several loess samples by application of IRSL and Post-IR OSL signals

respectively.The measured results present that the equiva- lent-dose depends on the heat temperature

especially depends on the cut-heat temperature

showing the equiva- lent-dose increases with the cut-heat temperature;a plateau of equivalent-dose appears at the 200—300℃preheat temperatures and the 200—240℃cut-heat temperatures

furthermore

the equivalent-doses estimated by IRSL and Post-IR OSL signals respectively are close to each other

which resulted from the similar sensitivity change directions of optical stimulated signals and their smaller change ranges in the measurement cycles using the various tempera- tures of pre-heat and cut-heat.This suggests that the 200—300℃pre-heat temperatures and the 200-240℃cut-heat temperatures are fit for dating young Holocene loess samples.
