Hydridic Earth theory

|
The Hydridic Earth theory is a theory proposed in 1968 by Soviet geologist Vladimir Larin. The theory contradicts the generally accepted views on the Structure of the Earth. Starting with the first principles, Larin proposed an explanation for the observed distribution of elements throughout the Solar system. Solar wind in the primordial system pushed elements away from the center. The elements with lower ionization potentials were trapped by the Sun's magnetic field and held closer to the sun, the elements with higher ionization potentials were pushed to the outer fringes. Assuming that the primordial abundance of the elements was similar to the current composition of the sun, the scheme accounts for the present rocky and metallic inner planets and gaseous outer planets. The described distribution scheme suggested that Earth must contain orders of magnitude more hydrogen than actually observed. To account for it, Larin made the most controversial suggestion of metallic composition for the middle and lower mantles in the form of metal hydrides. He suggested that the silicate-oxide composition is confined to the upper mantle and crust primarily.
