About AGES

Argon Geochronology for the Earth Sciences [AGES] is a premier geochronology laboratory located at Columbia University'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 Micromass VG5400 noble gas mass spectrometer to determine the age of mineral formation. Our research subjects include paleocllmate provenance studies, magmatic events and deep earth time.
