Uranium 235 decays to lead 207, and Thorium 232 decays to lead 208.In addition there is another stable isotope, lead 204, that is entirely primordial and does not form via radioactive decay at all.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.So, we rely on radiometric dating to calculate their ages.Answer 2: Yes, radiometric dating is a very accurate way to date the Earth.We know it is accurate because radiometric dating is based on the radioactive decay of unstable isotopes.The uranium and thorium decay systems offer a multitude of radiometric dating options.Uranium 238 decays through a series of steps to Lead 206.

As uranium decays radioactively, it becomes different chemical elements until it stops at lead. This is an enormous branch of geochemistry called Geochronology. It is an accurate way to date specific geologic events.Uranium minerals themselves are too uncommon to be very useful in dating.The most common dating method involves the use of minerals like zircon and monazite that are relatively common in granitic rocks.
