Hawaian island chain hotspot Argon-Argon ages
Ar-Ar Ages (millions of years) and distances (km) from Kilauea along the trend of the chain of Hawaian volcanic islands and other seamounts that are believed to have been created by a moving "hot spot".
A data frame with 10 observations on the following 6 variables.
Measurement error; 95% CI
Total uncertainty (+)
Total uncertainty (-)
Distance in kilometers
Note that measurement error is small relative to geological uncertainty. Geological uncertainty arises because lavas are likely to have erupted, over a period of up to 2 million years, somewhat after passage over the hot spot's centre. Dredging or drilling will in general have accessed larvas from the younger half of this interval. Hence the asymmetry in the geological uncertainty.
