Profile home

Fred Jourdan is a geochronologist and geochemist.
Fred's research focuses on the application and development of the 40Ar/39Ar chronometer to establish temporal constraints on large igneous provinces and impact craters. He also has a strong record in the technical development of the 40Ar/39Ar dating technique including 39Ar and 37Ar recoil, standard intercalibration, inherited 40Ar and investigation of the 40Ca*/40Ar* branching ratio. He is the director and primary user of the Western Australia Isotope Facility and is involved in all the collaborative projects involving this facility. His expertise in applying the 40Ar/39Ar dating technique to a range of geological problems is demonstrated by numerous collaborations involving e.g., the thermochronology of shear zones in Argentina, Spain and Australia, the geochronology of oceanic islands and study of the influence of alteration on the 40Ar/39Ar chronometer.
Fred developed skills in noble gas (40Ar/39Ar), thermal ionization (Sr, Pb isotopes) and MC-ICP (Nd, Hf isotopes) mass spectrometry during his Masters at the University of Geneva, Switzerland, his PhD at University of Nice-Sophia Antipolis, France, and his postdoctoral research at Berkeley Geochronology Center and the University of Berkeley, USA. He has also used microprobe and LA-ICPMS analysis at the University of Lausanne, Switzerland, and also has experience of clean laboratory sample preparation techniques including the use of ion exchange columns, acid preparation, chemical abrasion and thermal annealing. In 2007 he was appointed manager of the Western Australia Argon Isotope Facility, part of the John de Laeter Centre for Mass Spectrometry
