rbtree, Yup! jordan just verified the miracle. Except that the "new" theroy is that Pt migrates. Laughable at best. Guess I shouldn't be so hard on these lemings, I suppose Pt does migrate, an inch a million years! And to consider that bender and spielman overlooked all that "black" stuff than bottomed out on the shaker tables. They must have thought it was Fe. Equally laughable! IMHO
