From: The Quaternary Kurobegawa Granite: an example of a deeply dissected resurgent pluton
238U–206Pb age distributions (histogram, probability density plot) for zircon younger than 10 Ma for (a) the Kurobegawa Granite (including ~ 2 Ma portion) and (b) the Jiigatake Volcanics. The inset in (a) shows the result of age peak deconvolution using Isoplot35. The deconvolution was performed for ages < 1.55 Ma to analyze grouping of zircon ages after the ~ 1.55 Ma Jiigatake eruption. In (b), individual grain ages with 2σ uncertainty are also plotted. n = number of grains plotted.
