Chlorine 36 dating method

Rated 3.89/5 based on 535 customer reviews

Because of the reaction of cosmic rays with elements in minerals, chlorine-36 accumulates in rocks exposed at the earth's surface.

This suggests that the ratio of chlorine-36 to stable chloride can be used as a geochronometer.

Without the large datasets necessary to provide the statistical basis for calculating quantitative uncertainties, reporting the analytical uncertainty is the only real option.

The CRONUS-Earth Project produced datasets appropriate for this assessment.
