Comment:
Plateau age and Isochron age were calculated from 700, 800, 850, 950, and > 1300°C fractions. lambda = 5.543x10**-10 yr**-1, lambda-e = 0.581x10**-10 yr**-1, 40K/K = 0.0001167, total fusion age = 1/lambda ln [1 + J(40Ar/39Ar)total], (40Ar/39Ar)total = SUM-i-fi(40Ar/39Ar)I, fi = 39Ar fraction released. Empty cells = no data.
