Application of Recent Advances in Exploration Geochemistry

Dr Dennis Arne Telemark Geoscience May 2021 In this seminar Dennis Arne reviews the application of three recent advances in exploration geochemistry: the use of clay separates in the analysis of surficial materials, levelling of geochemical data for variable lithological background using principal components, and the application of machine learning to regional geochemical targeting. The advantages and limitations of these approaches are illustrated through the use of applied case studies. Dennis Arne has nearly 30 years experience in geology and applied geochemistry globally. He has overseen regional geochemical exploration programs in the Yukon, Nunavut and northern Quebec in Canada, the USA, eastern Australia, Suriname, Sudan and Laos. Dennis is currently director and principal consulting geochemist at Telemark Geosciences.
