To determine the approximate age of a rock, samples are crushed and then mounted onto epoxy pucks.

To determine the approximate age of a rock, samples are crushed and then mounted onto epoxy pucks. The samples are then blasted with lasers and heated to temperatures as hot as the surface of the sun to break them down into their constituent atoms. The chemical makeup and age are then determined using the mass spectrometers in the lab.
