Fig. 2From: First report of (U–Th)/He thermochronometric data across Northeast Japan Arc: implications for the long-term inelastic deformationEffective uranium (eU) versus (U–Th)/He grain age of zircon. The vertical error bars denote the ±1σ, ±2σ, and ±3σ ranges. The two horizontal red lines indicate the weighted mean age +95% confidence interval (CI) and −95% CI, respectivelyBack to article page
