Fission-track ages in Shimanto Belt on the forearc side of the Southwest Japan Arc. Age data were obtained from the low-temperature thermochronological database v.1.05.00 (Sueoka and Tagami 2019) and references therein. The pooled FT ages of 19 sedimentary and alteration-zone samples from this study are plotted at location HJG1 on the map; although the central age was adopted for zircon in the main text, the pooled age of all the grains is shown here for comparison with the reported ZFT dates. The geologic map was modified after Wakita et al. (2009). Active fault traces and Quaternary volcanoes are from Nakata and Imaizumi (2002) and Committee for Catalog of Quaternary Volcanoes in Japan (1999). [hi-P, high-pressure; S.B., Shimanto Belt]
