I wonder whether there are alternative ways of interpreting the isotopic data.

The isotopic data is OIB-type, which is favourable to the hot-spot hypothesis.

The significance of the isotopic data has, however, been called into question.

Other researchers proposed possible alternatives to living things that would explain the isotopic data (involving chemical alteration during metamorphism) and microfossils (mineral structures).

However, isotopic data suggests that preservation of Cordilleran lithosphere implies Cordilleran thinning is not a sufficient answer for Sevier and Laramide flat subduction.

The isotopic signature can then be compared with known isotopic data and the likely history of the nuclear material can be pieced together.

Although geological and isotopic data support an East Antarctic fit with western Laurentia, alternative reconstructions favor the juxtaposition of Australia, Siberia, or South China.

Many methods of determining baseflow residence time have been developed, mostly involving mathematical models using a convolution integral approach with isotopic or chemical data as the input.

One of the baboons had distorted isotopic data, so the other's oxygen isotope values were compared to those of modern-day baboon specimens from regions of interest.
