Prof. Xueqiu Wang works as a geochemist, senior geochemists and research fellow at the IGGE since 1989. He has 37-year experience in exploration geochemistry, geochemical mapping and global geochemical baselines at the Institute of Geophysical and Geochemical Exploration (IGGE). His research led to discovery of 16 large gold and 4 rare earth element deposits. He has published 2 books and 323 papers with 10742 citations. He was awarded for the National-class Scientific Talent of the New Century National Hundred, the Thousand and Ten Thousand Talent Project of China in 2004，the 70th Anniversary Commemorative Medal of the Founding of the People's Republic of China in 2019, the China National Prize for Science and Technology Progress Award in 2012, the First Prize of the Ministry of Natural Resources in 2021, the Li Siguang Prize, which is the highest honor of geology in China awarded by the Li Siguang Prize Committee, the AAG Gold Medal in 2026. He, as a professor at both academy and universities, have supervised 6 Post-doc, 25 PhD and 9 Master students. Hehasservedtotheinternationalscientificcommunity as a regional councilor (1998-2022) and a fellow (2008-present) of the AAG, a co-leader for the IUGS Commission on Global Geochemical Baselines (2008-2020) and an executive director of UNESCO International Centre on Global-scale Geochemistry (2016-present). He is initiated the International Big Science Program of Chemical Earth in 2016, which has provided training courses on geochemical mapping/explration for 856 participants from 52 developing countries and the national geochemical atlas for 13 countries of Mongolia, Laos, Cambodia, Uzbekistan, Tajikistan, Papua New Guinea, Madagascar, Ethiopia, Zimbabwe, Kyrgyzstan, Colombia, Peru, and Turkey.

His presentation will highlight how geochemical mapping, from nanoscale metal migration mechanisms to global-scale geochemical baseline patterns, has guided the discovery of major gold and heavy rare earth element deposits in China.
