Geochronologists Refine Rock-Dating Method Using Known Pompeii Eruption Date
Researchers used the historically documented date of Mount Vesuvius's eruption, recorded by Pliny the Younger as August 24, 79 CE, as a real-world check on a mineral dating technique. By comparing the known eruption date to results produced by the method, scientists were able to identify and correct discrepancies in how the technique measures time.
