Ages of CVF. (a) U/Pb concordia diagrams for zircon from A1. (b) U/Pb concordia diagrams for zircon from A4. Error ellipses are at 1σ level, and the calculated ages are at 95% confidence. (c) Age spectra of step-heating Ar-Ar analysis from A1. (d) Inverse isochrons of Ar-Ar age determination from A1. Note that Ar-Ar determination showed overestimated errors where MSWD represents the mean square of the weighted deviates (York 1969).
