Uranium dating examples, how do we determine the age of a rock?

Applications of Nuclear Chemistry. BERKELEY — A new study by geologists at the Berkeley Geochronology Center and the University of California, Berkeley, improves upon a widely used dating technique, opening the possibility of a vastly more accurate time scale for major geologic events in Earth's history.
