The 2025 edition of the annual Goldschmidt Conference will be held in Prague next week.

For starters, Victor Goldschmidt basically founded the modern science of cosmochemistry. He named the element categories- lithophiles, chalcophiles, siderophiles, and atmophiles- we use today to parse differentiated mantles, crusts, and cores. His namesake event is then a yearly review of cosmochemistry, geochemistry, and meteoritics. Since the Earth (and others) accreted from asteroids, and still gather meteorites and dust, the Goldschmidt Conference and its workers and papers are highly relevant to this blog. Just look at the program, you’ll agree. Highlights:
