Throughout the year the focus was on identification of multiple populations of zircons of similar ages in igneous samples. This project investigates the causes of limitations to U-Pb dating of minerals by LA-ICP-MS, with the aim of enhancing laboratory practices and instrumentation parameters to lower systematic errors and improve precision. Zircon is the primary mineral investigated; however, ongoing investigations for apatite, uraninite and monazite are currently underway. A paper describing the effects of various analytical parameters on the accuracy and precision of U-Pb dating of zircon was published in the Journal of Analytical Atomic Spectrometry.

September 16, 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. To date, zircons - known to many as a semiprecious stone and December's birthstone - have often produced confusing and inaccurate results. Zircons have produced complicated data that are hard to interpret, though people have pulled dates out," said Mundil, a former UC Berkeley postdoctoral fellow now at the BGC, a non-profit scientific research institute dedicated to perfecting dating techniques for establishing the history of Earth and life on Earth.
