Abstract
A light component in the Earth's outer core could account for its apparent lower density and higher seismic parameter than pure iron. On the basis of shock data for iron and iron–nickel, Birch and McQueen and Marsh concluded that the outer core was less dense than pure iron by 10 and 8 weight %, respectively. To account for these discrepancies both sulphur and silicon have been proposed as alloying elements with iron in the outer core.
