Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.Thus the current ratio of lead to uranium in the mineral can be used to determine its age.The method relies on two separate decay chains, the uranium series from Pb) leads to multiple dating techniques within the overall U–Pb system.Geologists often need to know the age of material that they find.They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.
