Lead uranium dating

Though the measurements of these elements are very precise, the assumptions upon which their usefulness as a clock rests are questionable at best.In a article on Brennecka’s findings, Gerald Wasserburg, emeritus professor of geology at Caltech, commented, “Everybody was sitting on this two-legged stool claiming it was very stable, but it turns out it’s not.” To be fair, however, it wasn’t “everybody” who claimed this.However, some Christians suggest that the geologic dating techniques are unreliable, that they are wrongly interpreted, or that they are confusing at best.

In 2005, sedimentologist Steve Austin performed a test of the lead-lead isotope clock assumptions in earth material, and found data that nullified the idea that the decay rate has been constant.Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.So, it is not surprising that Brennecka’s team has now found a need to tweak the age formulas used for dating meteoritic material.Although it is apparent that millions of years worth of decay—at today’s slow rates—has occurred in isotope decay systems, it is clear that the decay occurred rapidly, during a period of extreme acceleration. Wiens has a Ph D in Physics, with a minor in Geology.His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.Even the solar system has been dated using one of these systems, by measuring the amount of a decaying element and comparing it to the amount of its stable (decayed) daughter material in meteorites.However, a recent analysis using state-of-the-art equipment found that a basic assumption underlying one of these clock systems needs to be re-evaluated.Even though the Earth's age is never mentioned in the Bible, it is an issue because those who take a strictly literal view of the early chapters of Genesis can calculate an approximate date for the creation by adding up the life-spans of the people mentioned in the genealogies.Assuming a strictly literal interpretation of the week of creation, even if some of the generations were left out of the genealogies, the Earth would be less than ten thousand years old.
