Isotope #geochemist. Climate #scientist. Concerned #citizen. Person of precision, but one who knows when to sacrifice precision for accuracy. Studying past records of #climate and #carbon cycling since 1999. Frustrated that our scientifically advanced society seems impervious to scientific advice. Same handle on Xitter, but fully posting in the #fediverse since Nov. 2022.

The Earth does not have a good record of continental crust, or even plate tectonics, for the first 500 million years of its life. A new model shows that the early crust was simply too soft to preserve continental crust or behave like modern plate tectonics because of repeated impacts from large asteroids and associated heat. Without a record of such impacts in Earth's early, unpreserved crust, researchers looked toward the moon to assess how often and how big the early impacts would have been, and modeled heat flux into the mantle from those impacts.

💁🏻♀️ TIL: 🌋✨ #MountErebus on #RossIsland, #Antarctica, emits microscopic #crystals of elemental gold in its volcanic plume.
Scientists found faceted #gold particles up to 60 micrometers wide in #snow up to 1,000 km away. The #volcano releases about 80 grams of gold dust daily, but how the crystals form remains an open question.
