In our OSU Argon Geochronology Lab we employ the 40Ar/39Ar geochronology method to determine how hotspots evolve and interact with the lithosphere, in quantifying rates at which large igneous provinces are constructed, in deciphering the early history of the Earth and Moon, in tracking transport pathways of terrigenous sediments from rivers to deep-sea sediments, and more.
Our laboratory is equipped with two noble gas mass spectrometers for carrying out 40Ar/39Ar age determinations. We have two brand-new Thermo Scientific ARGUS VI multi-collector (installed in 2012 and 2015) with five fixed Faraday detectors and one ion-counting CuBe electron multiplier.
Since 1977 investigators, students and post-docs in our laboratory have produced 40Ar/39Ar age data that appeared in more than 195 peer-reviewed publications and in 31 Senior, MSc and PhD theses. This long list of papers could not have been possible without the more than 100 visitors over the last decades and our numerous national and international collaborators.
