Name:

Hawaian island chain hotspot Argon-Argon ages

Description:

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".

Variables:

A data frame with 10 observations on the following 8 variables.

age: Ar-Ar age
CI95lim: Measurement error; 95% CI
geoErr: Geological Uncertainty
totplus: Total uncertainty (+)
totminus: Total uncertainty (-)
distance: Distance in kilometers

Details

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.
