Erratum: Post-IR IRSL dating of K-feldspar from last interglacial marine terrace deposits on the kamikita coastal plain, northeastern Japan

The original version of this article contained incorrect calculation of recombination centre density, ρ’, and therefore all ρ’ and fading-corrected age were re-calculated. This erratum provides corrected Table 3, Fig. 4, Fig. 6 and Fig. 7 , as well as a list of corrections in the text.

Results of plRIR dating using different first IR stimulation temperaures. n is number of aliquots, ρ' is the dimensionless recombination centre density (Huntley, 2006). Residual dose was D_e after artificial sunlight bleaching for 3 h except for modern beach sand (gsj14-019) which was bleached for 800 h. Fading correction was performed based on Kars et al. (2008) and Kars and Wallinga (2009). To calculate the uncorrected ages, residual dose of modern beach sand (gsjH-019) was subtracted from D_e of each sample. D_o values were calculated based on Wintle and Murray (2006). ^a Terrigenous sediments.^b If the average g-value of samples from site 2 was lower than zero, fading correction would not performed.

Fading test results. (a) Typical results for sample gsj13-039; (b) g-values obtained with different first IR stimulation temperatures for gsj13-039 and gsj13-094. The error bars show one standard error.

(a) Uncorrected and (b) corrected pIRIR ages of gsj13-039 and gsj13-094 obtained with different first IR stimulation temperatures. The error bars show one standard error.

Columnar sections as in Fig. 2. For sites 1 and 2, the fading-uncorrected and -corrected ages of the pIRIR_50/290 and pIRIR_200/290 signals are shown with one standard error. For site 2, the fading corrected ages of pIRIR_200/290 signals were not calculated because the average ρ’ value was lower than zero. For each site, the vertical gray bar shows the expected age range.
