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 … WebProvenance and thermal history of the Paleogene Orca Group, eastern Prince William Sound, Alaska, using U-Pb and fission track dating of detrital zircon Geological Society of America May 2015
