Definition of fission-track dating in English:

fission-track dating

noun

mass nounGeology

A technique for establishing the age of a mineral sample from its uranium content. It involves microscopically counting tracks produced by uranium fission fragments and then establishing the existing concentration of uranium by counting again after irradiating the sample with neutrons.
〔地质〕裂变径迹计时，裂变径迹定年
Example sentencesExamples
- Vitrinite reflectance data and apatite fission-track dating have been widely applied across northern England and the adjacent northeastern Irish Sea, but with some controversy from assumptions.
- The cooling history of the pluton is documented on the basis of U-Pb, 40 Ar / 39 Ar step-heating and fission-track dating.
