Fission track dating
Fission track dating is a radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium-bearing minerals and glasses. Fission-track dating is a relatively simple method of radiometric dating that has made a significant impact on understanding the thermal history of continental crust, the timing of volcanic events, and the sourc… WebMay 20, 2011 · They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in numbers of years. This is different to relative …

WebApatite fission track thermochronology. The basics of apatite fission track (AFT) thermochronology have been summarised in Gallagher et al. (1998) and here we provide a brief overview drawn from this earlier publication. Fission tracks are linear damage features formed from the spontaneous fission of 238 U, which occurs in trace amounts (10 ... WebProduct Information. This book is focused on the basics of applying thermochronology to geological and tectonic problems, with the emphasis on fission-track thermochronology. It is conceived for relatively new practitioners to thermochronology, as well as scientists experienced in the various methods. The book is structured in two parts.
