"The biggest (misconception) in general is people think that the mantle is made of magma, or the mantle is molten or liquid.” Earth sciences professor @brenhinkeller.bsky.social discusses misunderstandings about the Earth’s structure with Indy100.
You probably don’t know this about the Earth – and museums get it wrong too
So much is made of scientific discoveries in outer space, as we try to broaden our horizons and explore the surface of Mars, but in reality, many of us don’t know much about things right below our fee...

Who’s guilty of the discrepancy between minerals and whole-rock chemistry in plutons? Melt extraction might be innocent—mineral reequilibration is likely the real culprit! Fresh out on Pi Day by me, Brenhin @brenhinkeller.bsky.social, & Changqian! doi.org/10.1029/2024...
Amphibole Compositions Record Cold Post‐Emplacement Reequilibration in Plutons
Melts predicted from mineral compositions in arc plutonic rocks do not match bulk compositions, a discrepancy absent in volcanic rocks Neither bulk crystallization nor melt extraction can fully e...
