Comment:
Correction factors used are (39Ar/37Ar)Ca = 0.0039, (36Ar/37Ar)Ca = 0.00029, (40Ar/39Ar)K = 0.031. Errors given in the apparent ages indicate 1 sigma. Empty cells = no data.

| 4 | Temperature, technical | T tech | °C | Yanagisawa, Masahisa | # = Because of small 36Ar peaks, it was difficult to assign error estimates (at the 900°C, 1000°C fraction of Core 439-33 and the 950°C fraction of Core 439-36). After the correction for Ca-induced 36Ar, 36Ar value became negative (at the 1000°C fraction of Core 439-33). However, these did not affect the apparent ages | |
