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. WebJul 3, 2024 · The fission track technology has been applied to many geological applications with advantages of less sample consumption, lower closure temperature and wider dating range. For example, fully or partially annealed samples can effectively record the cooling-exhumation history and constrain the onset of thrust fault activity. The relationship …
