So, by comparing the argon to potassium ratio in a volcanic rock, we should be able to estimate the time since the rock formed. Related Media. Boltwood had conducted studies of radioactive materials as a consultant, and when Rutherford lectured at Yale in[28] Boltwood was inspired to describe the relationships between elements in various decay series. It is conceptual.
