Uranium 238 dating rocks

There is thus no impediment to accepting and using the Bible’s account of Creation and the Flood as a reliable framework for unravelling the history of the earth and the Pb isotopes found in its minerals and rocks.

Radioisotope dating of minerals, rocks and meteorites is perhaps the most potent claimed proof for the supposed old age of the earth and the solar system.

All the unprovable assumptions ultimately depend on an assumed deep time history.

Its rejection is recognized as fatal to the earth’s claimed age of billions of years.

There is also primordial Pb that the earth acquired when it formed, its isotopic composition determined as that of troilite in the Canyon Diablo iron meteorite.

Subsequently new crustal rocks formed via partial melts from the mantle.

(1969), have not been accompanied by any comparable improvement in the accuracy of the decay constants (Begemann et al.The absolute ages provided by the radioisotope dating methods provide an apparent aura of certainty to the claimed millions and billions of years for formation of the earth’s rocks.Many in both the scientific community and the general public around the world thus remain convinced of the earth’s claimed great antiquity.Various methods have been devised to determine this initial or common Pb, but all involve making unprovable assumptions.Zircon does incorporate initial Pb when it crystallizes. It cannot be proven that the Pb in apparently cogenetic U- or Th-free minerals is only initial Pb, and that it is identical to the initial Pb in the mineral being dated.
