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… WebThe main methods I use are low-temperature dating techniques such as fission-track analysis and U-Th/He dating applied to bedrock and sediments to quantify the thermal history of Earth's upper crust. These data are combined with other geo- and thermochronology data, structural measurements, geomorphology, sedimentology, …

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. WebMay 11, 2011 · Fission track dating.

Uranium is present in many different rocks and minerals, usually in the form of uranium-238. This form of uranium usually decays into a stable lead isotope but the uranium atoms can also split – a process known as fission. During this process the pieces of the atom move apart at high speed, causing damage to the rock or mineral.
