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.
Lamont paleoclimatologist William D’Andrea studies past climates to see how societies such as the Vikings and the Rapanui of Easter Island dealt with environmental change. His work may help us adapt to a hotter future.
