  • Hot Enough to Melt Iron Earth's core is divided into a fluid outer core and a solid inner core, both composed predominately of iron at extremely high pressures and temperatures. The boundary between these two regions is largely controlled by the melting point of iron at ∼330 GPa, which in turn influences heat transfer and geodynamo generation. Anzellini et al. (p. 464, see the Perspective by Fei) compressed iron in a laser-heated diamond anvil cell, tracking its structure and texture by using… CONTINUE READING
