Dating rocks using radioactive isotopes
As Christians it is of great importance that we understand God's word correctly. Plotting an isochron is used to solve the age equation graphically and calculate the age of the sample and the original composition.
Previously, dating of anthropology sites had to rely on dating of geologic layers above and below the artifacts.
The bottom two entries, uranium and thorium, for tips are replenished as the long-lived uranium atoms decay.Some of the atoms eventually change from one element to another by a process called radioactive decay.Since most cave formations have formed relatively recently, formations such as stalactites and stalagmites have been quite useful in cross-calibrating the carbon record.The other method relies on actually counting the atoms of each isotope, not waiting for some of them to decay.The radioactive materials produced in a nuclear reactor are radioactive because of instability in the nucleus of the atoms of the radioactive materials.
