Summer of 2005 was full with exciting fieldwork. First, I visited Iceland, where Olgeir Sigmarsson and myself collected important rocks for single crystal isotopic studies here at Oregon and at Clermont Ferrand. Then, I went to Kamchatka, where graduate student Sara Auer and myself worked on collecting a complete section of stratigraphic tefra layers of Klyuchevskoy volcano, while talking to scientists at the Institute of Volcanology and Seismology in the city of Petropavlovsk. Together with Vladimir Leonov and Vera Ponomareva, I have also examined the caldera record of this exciting area and its thick continental crust. We’ll soon be selecting major ignimbrites for Ar-Ar dating and oxygen isotope examination in the framework of my newly funded NSF proposal.
