Strong new evidence suggests that primordial material from the planet’s center is somehow making its way out. Continent-size entities anchored to the core-mantle boundary might be involved.
I was trying to answer OP’s question “isn’t that what volcanoes are” by clarifying that volcanoes are formed by the release to the surface of magma from the mantle. If they are now discovering there is also some core material mixed in with the lava in some volcanoes, that’s interesting and we might mention that as a minor component in those cases. But to say regarding material from the core, “that’s what volcanoes are” would be inaccurate. That would be some weird metallic-ass volcano if it was made from outer core material.
Precisely: the core is primarily iron, in mass, with nickel probably being the 2nd by-mass component. I’ve read that hydrogen is about 10% of the core’s mass ( metallic, obviously ), & that is why the seismic-refraction-index is as low as it is. Platinum, iridium, osmium, uranium, etc, all the heavy stuff, is in there, too.
( that is why the iridium-rich layer covering the entire planet right when the dinosaurs got extincted is significant:
it had to come either from a nickel-iron type impactor, XOR it had to come from volcanoes which somehow got core-metals in them: there’s no other source for that much iridium, locally to this planet.
The fact that the impactor has been tested to be carbonate rock, & NOT a nickel-iron body, to me, proves that the impact produced that burst of volcanoes on the opposite side of the planet
( those volcanoes exist: some have claimed that the impact didn’t cause dino-extinction … that it was ONLY those volcanoes ),
…and to me proves that the total input of both impact and burst-volcanoes’ energy-expressions is what killed-off the dinosaurs.
Lava isn’t heavy-metals-rich normally: we’re talking thousands-of-km distance between the bottom-of-the-crust & the outer-liquid-core ( the inner-solid-core is inside the outer-liquid-core ), magma is a HUGELY thick layer.
