Fission track dating is based on the microscopic observation and counting of etchable tracks left by the spontaneous fission of uranium in minerals. Since its development in 1963 the method attracted a steadily growing interest from geologists and geochronologists throughout the world. Apart from its relative experimental ease the success must be mainly ascribed to the specific ability of the method of unravelling the thermal and tectonic history of rocks, a potential which only became fully exploited during the last decade with the systematic introduction of track size analysis. The present work is the first one to deal entirely with fission track dating covering all of its aspects from the origin of the fission tracks, the basis of track etching and fading, the various dating techniques as well as practical procedures and the geologic interpretation to the most recent applications in geology and archaeology.
