Paper number 95TC00932, Ar/Ar geochronology of ultrahigh-pressure metamorphism in central China, B.R. Hacker and Q. Wang). Complete 40Ar/39Ar data. T: temperature; 40Ar: moles of 40Ar corrected for blank and reactor-produced 40Ar; 40Ar*/39ArK: ratio of radiogenic 40Ar to 39Ar produced by irradiation of 39K; 37Ar/39Ar: ratio of corrected 37Ar and 39Ar; 36Ar/39Ar: ratio of corrected 36Ar and 39Ar; K/Ca: inferred K/Ca ratio; · 39Ar: cumulative 39Ar released; 40Ar*: radiogenic fraction of 40Ar. Uncertainties for isochron and spectrum ages include uncertainty in J factor. Alteration minerals are shown in parentheses after their host phase.
