Uranium dating problems - More Bad News for Radiometric Dating - Computer Science


This data is compared to a curve called the Concordia diagram. This diagram has been made by using the ratio of uranium to lead of all the rocks dated with this method and their assumed age. Scientists know that there are geological events that can disturb the zircon and release the lead created from the uranium. This would reset the time recorded by this method. To try to account for this, a radiometric dater will use many different samples and use the ones that fit the Concordia curve. If they do not fit, it is assumed that it signifies a large geological event [1] .

An hourglass is a helpful analogy to explain how geologists calculate the ages of rocks. When we look at sand in an hourglass, we can estimate how much time has passed based on the amount of sand that has fallen to the bottom.
