stshank, 29 days ago Wicked smart scientists calculate how long volcanoes on Jupiter moon Io have been active. Measure relative abundance of 2 sulphur isotopes belched into the atmosphere then reprocessed as crust — bias toward heavy sulphur. Compare ratio to early solar system meteorites. https://www.science.org/content/podcast/very-volcanic-moon-and-better-protections-human-study-subjects #Science #Vulcanism #Jupiter

stshank, 28 days ago @karlauerbach Neat! Also check out radioactive decay used for measuring the age of the Earth (lead and uranium) and of lava flows (argon and potassium). https://www.pbs.org/wgbh/evolution/library/03/3/l_033_01.html https://www.whoi.edu/know-your-ocean/ocean-topics/how-the-ocean-works/seafloor-below/volcanoes/how-old-is-that-volcano/
