Question

Quizplus · Accepted Answer

Fission-track dating is a chronometric dating method that is based on the tracks created by the spontaneous fission of uranium-238 in minerals such as zircon, apatite, and sphene. The number of fission tracks in the mineral is proportional to the time elapsed since it last experienced high temperatures. By counting the tracks and comparing them to a calibration curve, the age of the mineral can be determined.
