K-Ar data for whole-rock basalts at ODP Hole 105-647A (Table 1)

Alteration of basalt samples in the basement rocks of Site 647 produced a range of K-Ar ages from 35 to 71 Ma. Microprobe data indicate that an alteration phase contributes nearly 50% of the potassium in the samples. Thus, a component with uncertain argon-retention characteristics is considered resp...
