The Argon Geochronology for the Earth Sciences (AGES) lab is located at Columbia's Lamont-Doherty Earth Observatory along the Palisades Parkway in Rockland County, New York. Our lab measures Argon isotope compositions and concentrations, mainly of single mineral grains, on a VG5400 noble gas mass spectrometer to determine the age of mineral formation. Our research subjects include paleocllmate provenance studies, volcanoes and deep earth time.
