If I were to question it, I'd start with the elemental composition of planets without plate tectonic subduction.

They probably ought to call a geologist:
* tectonics doesn't drive convection. It only works the other way around.
* 'plates' can't exist in the lower mantle. It's all 'melt' down there.
* liquids cannot exert stress or strain energy.
* temperature and pressure is good enough to get diamond.
* it takes a linear accelerator to create a neutrino.
* cosmic neutrinos pass right through all of Earth's matter, making their passage a 'non-experience' for nearby magma. They'd have to prove some special physics for any so-called 'geoneutrino' to collide with Earth's matter any differently.
* all pre-solar system building blocks exist within the asteroid belt. Between rocky and metallic meteorites, we have a full accounting for all the elements which created Earth, Mars, and Venus.
Best I can tell.
* the most 'exotic' substance comes from the Apollo-15 CREEP basalt from the Moon, created 3.8-billion years ago, when a meteor swarm struck the lava lake which became a naked-eye, Mare Imbrium, as seen from Earth today. A very special shock-formed, yellow glass, unseen anywhere else in the Solar System.
