Fig. 7From: Thermochronology of hydrothermal alteration zones in the Kii Peninsula, southwest Japan: an attempt for detecting the thermal anomalies and implications to the regional exhumation historyThermochronometric data plotted against distance from alteration zones. The distances were calibrated against the strike and dip of the alteration zones. Error bars for data are ± 1 standard error for FT lengths and ± 1σ for FT ages and U–Pb ages. The ZHe data were plotted as single-grain ages ± 1σBack to article page
