Although zircon (Zr Si O) is most commonly used, other minerals such as monazite (see: monazite geochronology), titanite, and baddeleyite can also be used.

Where crystals such as zircon with uranium and thorium inclusions do not occur, uranium-lead dating techniques have also been applied to other minerals such as calcite/aragonite and other carbonate minerals.

There are over forty such techniques, each using a different radioactive element or a different way of measuring them.

Loss (leakage) of lead from the sample will result in a discrepancy in the ages determined by each decay scheme.

This effect is referred to as discordance and is demonstrated in Figure 1.

and most refined of the radiometric dating schemes.

It can be used to date rocks that formed and crystallised from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range. This mineral incorporates uranium and thorium atoms into its crystal structure, but strongly rejects lead when forming.
