Do we tell each other about our fun new #publications on here? It’s great to see “powering Earth’s ancient dynamo with silicon precipitation”, (http://doi.org/10.1029/2022GL100692). Fred Wilson leads an ‘all star team’ (thanks #reviewer2) to combine mineral physics and thermal history modelling to look at a possible way to explain observations of an early magnetic field on Earth.
I ought to have added a link to the #preprint … https://doi.org/10.31223/x5h34m
@a_walker Very cool! I seem to recall a paper a few years ago about silicate melts generating the ancient magnetic field in the lower mantle (when it was still molten)… I thought this was related to that at first, but no - we’re back in the core!
@allochthonous yep - I think that’s still on the list of possibilities but I don’t recall much follow up. I could well have missed something though.
