K/Ar Age Determinations on Drill Core from DVDP Holes 1 and 2
Four conventional K/Ar ages were determined on two samples from each of DVDP drillholes 1 and 2. Apparent ages (calculated using the new 1977 calibration constants) range from 1.21±0.11 m.y. to 1.34±0.23 m.y. for samples from 25.52m and 148.81m depth respectively in DVDP 1. Age determinations on DVD...
