New geochemical research indicates that existing theories of the formation of the Earth may be mistaken. The results of experiments to show how zinc (Zn) relates to sulphur (S) under the conditions present at the time of the formation of the Earth more than 4 billion years ago, indicate that there is a substantial quantity of Zn in the Earth's core, whereas previously there had been thought to be none. This implies that the building blocks of the Earth must be different to what has been supposed. The work is presented at the Goldschmidt geochemistry conference in Paris.
 

The researchers, from the Institut de Physique du Globe de Paris (IPGP) melted mixtures of iron-rich metal and silicate compounds, containing Zn and S, at high temperatures and pressures up to 80 GPa and 4100K* to experimentally simulate core-mantle differentiation at the time of the Earth's formation. They then measured how these elements were distributed (partitioned) between the core and mantle of their experiments. When they fed their results into computer models of the Earth's formation, they found that none of the canonical models can sufficiently reproduce the S/Zn ratio of the present-day mantle. This means that the current estimates of the Earth's composition, including its core, need to be modified, and therefore the way the core and mantle -- i.e. the Earth -- formed may also need to be revised.

Well, duh? Them science dudes obviously have never read Genesis. God didn't need no stink' n S/Zn to form nut' n. God just said, "Yo, let there be dirt!" And there was dirt all over the freak' n place dudes. Same thing with the oceans. Them science dudes think they are so freak' n smart. They don't know nut' n.

This could then affect how life formed.

 

It's possible we've been going about it the wrong way.

 

No doubt someone will com up with the outstanding revelation "see goddidit!"
