• 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 DVDP 2 are 1.16±0.03 m.y. and 1.32±0.16 m.y. for samples from depths of 62.38m and 173.93m respectively. The ages are statistically not significantly different from one another; and show the flows and pyroclastic units in DVDP 1 and 2 were erupted about 1.26 m.y. ago over a short period of time, probably less than 0.3 m.y.
