Basics of Fission-track Geo- and Thermo-chronometry: Revisiting Its History to Explore Future Potential

Abstract

Fission-track (FT) method observes linear dislocations in geological materials formed by nuclear fission of ²³⁸U. FT method provides information on thermal history of a sample below 300°C, together with geological dates. This report revisits the development history of FT method and suggests potential research target left unearthed.
