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). WebA full summary of the fission track dating results from RATE can be found on pages 218 and 238 of reference 13, available online. The published ages are taken from various …
