BOR-MING JAHN (BMJ) biographical memoir and brief introduction to BMJ’s scientific contributions and academic services
Abstract This memoir highlights the scientific and academic contributions of Bor-ming Jahn who passed away in last December. He is best known for his ability to draw novel insights about the Earth’s tectonics, evolution, and geological processes from in-depth field and laboratory studies of isotopic and elemental geochemistry. He is recognized as a global leader in the applications of geochemical and isotope tracers (Sr-Nd-Hf-Pb-O) to regional tectonic evolution, and made outstanding contributions to the formation of dominant juvenile crust (>70%) for the Phanerozoic Central and Northeast Asian Orogenic Belts. He created the term “TTG” for tonalite-trondhjemite-granodiorite suites formed in ancient and present-day magmatic arc setting and is the first to date the oldest Chinese rocks and to constrain Triassic continental subduction for the Dabie-Sulu UHP terrane. He received numerous honors, and was the first Chinese Earth scientist to be the Editor-in-Chief of the celebrated Journal of Asian Earth Sciences , Elsevier. We are sad for his sudden passing; yet his scientific devotion and contributions will be remembered for decades to come.
