Ilmari Haapala received an MSc in geology and mineralogy in 1963, and PhD in 1966 at the University of Helsinki. He has worked as geologist, state geologist and acting head of the Exploration Department at the Geological Survey of Finland in 1966 –2001, and as professor of geology and mineralogy at University of Helsinki in 1982 –2002. Dr. Haapala has lead many Finnish and international research projects, including rapakivi granite projects in Finland, China, USA (New Mexico and Nevada) and Namibia. Organized eight international symposia. Edited several Finnish and English books on economic geology and granite petrology. Chairman of the Geological Society and Mineralogical Society of Finland. Member of the Finnish National Academy of Science and Letters since 1985.Fellow member of the Geological Society of America, the Mineralogical Society of Great Britain and Ireland, and the Geological Society of London. Roberto Dall’Agnol worked as geologist in the RADAM project during 1973–77 and completed his Doctor thesis at the Paul Sabatier University in Toulouse, France. He acted as professor of igneous petrology at the Geosciences Institute of Federal University of Pará, Brazil from 1980–2014. At present, he participates in the Graduate Program of Geology and Geochemistry of that institution and leads a research group in the Vale Institute of Technology in Belém, Pará, Brazil. Co-leader of the IGCP Project 510 (A-type Granites and Related Rocks trough Time) in 2005–10, IGCP Project 599 (Changing Early Earth) in 2011–14. Leader of the Project “Magmatism, crustal evolution and metallogenesis of the Carajás and adjacent provinces of the Amazonian craton” in 2000–06, and of other national geoscientific projects in Brazil until present. Guest editor of special volumes in Lithos, Journal of South American Earth Sciences, and Canadian Mineralogist Aku Heinonen studied geology and mineralogy in the University of Helsinki (UH) and graduated with his MSc in 2007 and PhD in 2012. He was employed as a teaching and research assistant, doctoral researcher, academic affairs officer, and postdoctoral researcher at the Department of Geology (later Department of Geosciences and Geography, UH) in 2007–16 and as a postdoctoral fellow at the Institute of Seismology (UH) in 2016–17. He worked as a Lecturer in Petrology (UH) in 2017–22 and was appointed as a Docent (adjunct professor, in petrology, UH) and as the director of the BSc Programme in Geosciences and MSc Programme in Geology and Geophysics (UH) in 2020. Heinonen worked as the director of the national FIN-GEO education collaboration network in 2020–2022 and in 2022 he was appointed as the Head of Science and Innovations at the Geological Survey of Finland (GTK). Heinonen participated in the IGCP 510 (A-type Granites and Related Rocks through Time) in 2007–2010 and conducted his doctoral and postdoctoral research on the isotope geochemistry of rapakivi granites and associated massif-type anorthositic rocks from southern Finland, northern Brazil, and southwestern USA in 2007–2016. He is a member and acting secretary of the Finnish National Committee of Geology and the upcoming Finnish National Delegate for the EuroGeoSurvey organization (2023–).
