    Zircon is a zirconium silicate mineral which is ideal for use in age-dating. The importance of zircon as an age-dating tool include; its good hardness (which means makes it resistant to metamorphism, mechanical and chemical weathering), it is easy to chip, it undergoes radioactive decay and leads to damaged crystals, it is commonly found at many localities, and it has a very high lead versus uranium ratio which is used to determine the age of the rock.
