Jeffrey Hedenquist

Jeffrey Hedenquist is an Adjunct Professor specializing in economic geology and mineral exploration. He holds a PhD from the University of Auckland (1983) and an honorary doctorate from Université de Genève (2014). His research focuses on epithermal gold deposits, porphyry copper systems, and hydrothermal alteration processes. He has authored over 100 papers on topics including ore genesis, exploration methodologies, and magmatic-hydrothermal interactions. Notable contributions include studies on the Khundii metallogenic province in Mongolia and the Far Southeast porphyry deposit in the Philippines.

• Professional Recognition: SEG Ralph W. Marsden Award (2013), SEG Silver Medal (2000)

His work bridges field observations with geochemical and isotopic analyses to unravel ore-forming processes. Recent research emphasizes advanced argillic lithocaps as exploration targets for underlying porphyry systems. He has pioneered techniques using shortwave infrared spectroscopy for mineral exploration and contributed to understanding volcanic vapor condensation mechanisms.

Key articles (2024–2016) highlight exploration strategies for epithermal systems, porphyry-copper linkages, and stable isotope applications in mineral systems. His interdisciplinary approach integrates geology, geochemistry, and geophysics to address global mineral resource challenges.
