Crystal Core?

Feb 1996

Quoted from the article by William J.Broad in The New York Times 4/4/95:

"NEW clues and theories are illuminating one of the most inaccessible and enigmatic parts of the planet, its inner core, suggesting that this mass of solid iron has a crystalline structure that may be responsible for a series of magnetic riddles observed at the earth's surface. . . ."

"Going further, some experts say it may be a solid crystalline structure of gigantic proportions. 'My hypothesis is that it's like a diamond in the center of the earth, just one single crystal,' Dr. Ronald E. Cohen, a geophysicist at the Carnegie Institution of Washington who is using supercomputers to model the core's structure, said in an interview. . . ."
