Fission track dating
WebAbstract Fission track analysis as a geological dating tool was first proposed in the early 1960s. The past 10 years has seen a major expansion in application to more general geological problems. This reflects advances in understanding the temperature dependence of fission track annealing and of the information contained in fission track length … WebThis discordance means that the U-Th-Pb and fission track dating methods give wildly different dates for the zircon samples measured, most of which strongly diverge from the secular age expected for the Middle Cambrian rock. Similarly, the fission track dating for the Late Jurassic samples gives results that diverge from the expected geologic age.

Another radiometric method that is used for samples from early human sites is fission track dating. This is based on the fact that a number of crystalline or glass-like minerals, such as obsidian, mica, and zircon crystals, contain trace amounts of uranium-2 38 (238 U), which is an unstable isotope.
