Fission track
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 … WebJan 21, 2024 · Fission-track dating: A technique that determines age of various minerals and glasses based on the trails of damage done by the spontaneous fission of uranium-238, the most abundant isotope of …
