Victor Goldschmidt, the geochemist, was serious. Goldschmidt, the geochemistry conference, is 70+ years more serious:

Ryugu and Bennu, as unaltered, early-Solar-System specimens in hand, tell us of our own history:

The Origin and Deep Cycles of Life-essential Volatile Elements on Earth and Rocky Planets, R. Dasgupta
“constraints on the chemistry of dissolution, solubility, and partitioning of LEVEs (C, H, N, and S)”
Electrostatic forces drive the formation of nanostructured hydroxide films on mica, Benjamin Legg
“to track the growth metal-hydroxide films (gibbsite, brucite, etc…) at the mica-water interface.”
Effects of surface heterogeneity on Rb+ sorption at the quartz (101)–water interface, Peng Yang
“the reactivity of mineral–water interfaces toward nutrients and metals.”
