Mineral age dating
God’s Word, on the other hand, provides the true history of the world—a world He created in just six days, all ready to be inhabited ( In their paper “Hadean age for a post-magma-ocean zircon confirmed by atom-probe tomography” Valley and colleagues interpret their research results through the lens of multiple levels of assumptions.
Each interpretation is built on the assumptions at that level and the interpretation from the previous level.
Because secular scientists like Valley believe the earth is 4.56 billion years old, they believe this little crystal has a lot to say about the earth shortly after it coalesced into molten rock from matter thrown from a solar nebula.
Oxygen isotope ratios in the crystal are consistent with formation in an environment that contained liquid water.
It is possible for the lead atoms—all believed to be the products of radioactive decay—to move.
Therefore, many debate the accuracy of these clocks in the rocks.
The little crystal Valley’s group analyzed supposedly dates to a time some scientists call the Hadean age.
Confined as they are in these crystals, many scientists believe that the ratio of parent radioactive uranium to daughter lead atoms in zircons can be used to calculate the ages of the crystals.Do zircons—crystals of zirconium silicate—contain clocks you can trust?Crystals of zirconium silicate can be found inside many sorts of rocks in the earth’s crust.Though apparently impervious to their environmental conditions, zircons can be ravaged from within.Radiation emitted from trapped uranium and thorium atoms can disrupt their crystalline structure.
The oldest known fossils—stromatolites—carry a conventionally assigned age of almost 3.5 billion years, far younger than this zircon.
