Just this one fact totally upsets data obtained by C dating. Why is it that the 'dates' agree with each other if they're wrong? We now have a good idea why most radiometric dating methods give inflated ages: So, if you happened to find a rock with 1 microgram of potassium and a small amount of argon, would you conclude that the rock is 1. Since the rate at which various radioactive substances decay has been measured and is well known for many substances, it is tempting to use the amounts of these substances as a proxy for the age of a volcanic rock.
Each one has a different half-life and a different range of ages it is supposed to be used for.
Although this technique looks good at first, carbon dating rests on at least two simple assumptions. All radiometric dating methods used on rocks assume that the half-life of the decay has always been what it is today. HistoriesII. Genesis creation narrative and Chronology of the Bible.
