Fission track dating time range
WebJan 1, 2024 · Spontaneous fission of 238 U occurs at a known constant rate, meaning fission tracks can be used to date geologic materials (Price and Walker 1963).Fission track dating was first applied successfully to natural glass (Fleischer and Price 1964) and today is most commonly applied to apatite and zircon.Fission decay follows the … Webtime scales best suited to the measurement of ages of the order of millions of years. However, one of the newest techniques, fission-track dat ing,1 will be shown here to have a definite though limited utility for dating man-made glass objects. This technique has been used suc cessfully for the dating of minerals and of natu
