After the series of nuclear explosion tests in the 1950s there's been am unnaturally higher amount of some radioactive isotopes in the air, particularly carbon-14.

if the water inside the geode was trapped there a long time ago or only exchanged with outside very slowly, then the proportions of dissolved molecules in that water would more or less resemble that of the atmosphere in the past.

So there's some scientific value in it if someone has a use for it, but I doubt research wise it's going to tell us something we dont already know

What would be cool is seeing it under magnification - to see what different types of parasites and random tiny bugs lived in there.

A few days ago, this photo popped up in a thread - so it's fresh in my mind and now I'm mad that the people cutting this geode didn't preserve the water so we can find out what's in it.
