How is zircon dating used to determine the age of geological samples?

Zircon dating is a method used to determine the age of geological samples by measuring the radioactive decay of uranium to lead within zircon crystals. By analyzing the ratio of uranium to lead isotopes in zircon crystals, scientists can calculate the age of the sample based on the known rate of radioactive decay. This technique is commonly used in geology to date rocks and minerals, providing valuable information about the Earth's history and the timing of geological events.
