Unlike many other dating techniques, fission-track dating is uniquely suited for determining low-temperature thermal events using common accessory minerals over a very wide geological range (typically 0.1 Ma to 2000 Ma). Apatite, sphene, zircon, micas and volcanic glass typically contain enough uranium to be useful in dating samples of relatively young age (Mesozoic and Cenozoic) and are the materials most useful for this technique. Additionally low-uranium epidotes and garnets may … WebThe “fission track thermochronology” is based on the radioactive decay by natural spontaneous fission of uranium 238 (238 U), where each fission generates a track (Wagner and Van den Haute, 1992). The fission tracks are generated with a constant velocity over geologic time, so the number of fission tracks in a mineral depends on the … nxg speakers any goodWebGiven that the spontaneous fission of 238U occurs at a known rate, the age of a mineral or glass can be calculated from the amount of uranium and number of spontaneous...
