If these crystals were pure, they would contain just zirconium, silica, and oxygen; however, uranium happens to have a similar arrangement of outer electrons to zirconium, and so as zircons form, "mistakes" are sometimes made, and uranium is substituted for zirconium.How can the formation of a rock be correlated with a particular ancient event?The answers to all of these questions lie in our understanding of the geologic processes that affect the deposition of radioactive elements.The zircon formation may have occurred tens to hundreds of thousands of years before the eruption and deposition.However, when dealing with rocks that are hundreds of millions of year old, the time between zircon formation and eruption really is short in comparison.
