Data Set Apatite fission track thermochronometry data from …

WebFission track dating is commonly used on apatite, zircon and monazite. It helps to determine the rates of uplift (for geomorphology studies), subsidence rates (for petroleum exploration and sedimentary basin studies), and the age of volcanic eruptions (this is because fission tracks reset after the eruption). WebFission-track dating is a suitable method for dating impact events. In the cases of many dated sites, impact glasses were usually used as fission-track recording material. The fission-track ages of the dated impact sites are given range from 4 ka to 300 Ma. In addition to the dating of impacts, fission-track studies can also reveal the howe art supplies

Fission track and luminescence dating — Science …

WebFission track dating is based on the number of 238 U spontaneous fission tracks accumulated in a mineral from the formation of the mineral. If the temperature of the geological body containing the mineral was too high to retain fission tracks, the tracks formed in this period would be completely lost. WebFission track dating is a radioisotopic dating method that depends on the tendency of uranium (Uranium-238) to undergo spontaneous fission as well as the usual decay process. The large amount of energy released in the fission process ejects the two nuclear fragments into the surrounding material, causing damage paths called fission tracks. ...
