As a billion U atoms decay, a sharp U halo forms. They are widespread in rocks as old as 3. There, they discovered depleted partially consumed U in isolated zones. The results suggest that the present-day global tectonic scheme was operative in the distant past as well. The same margin of error applies for younger fossiliferous rocks, making absolute dating comparable in precision to that attained using fossils. Third, depleted U was found where it should not be—near the borders of the ore deposit, where neutrons would tend to escape, instead of fission U. Magma , formed by melting deep within Earth, cuts across and hence postdates all units as it rises through the crust, perhaps even to emerge at the surface as lava. With a burst of more than electrons flowing through the center of this plasma sphere, the surrounding nuclei positive ions implode onto that center. Without absolute ages, investigators could only determine which fossil organisms lived at the same time and the relative order of their appearance in the correlated sedimentary rock record. However, Gentry believes, incorrectly, that on Day 1 of the creation, a billion or so polonium atoms were concentrated at each of many points in rock; then, within days, the polonium decayed and formed isolated parentless halos.

    Although we could not gain access into the mine, we all agreed that the intrusion cut up through the sedimentary layers. The truncated layers provide an easily determined depositional top direction.
