TO put this all to rest, I spoke with my cousin, Andrew Lorrey, who is a
graduate Geology student at U Maine, Orino. He said that the outer core
is molten, but the inner core is solid iron/nickel with a smidgen of
heavy elements. The inner core is NOT a single crystal, but as a solid
does have a crystalline structure, which is decidedly different than a
single crystal.
