In this lesson, we will learn how to use isotope ratios to estimate sample age and how to compare the advantages and limitations of radiometric dating methods.
Q1:
The decay of 129I produces 129Xe. The quantities of 129I and 129Xe in a meteorite suggest an age of 15 million years. However, other radiometric dating methods suggest the meteorite is 10 million years old. Which of the following is a possible explanation for this discrepancy?
