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 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 … raw meat sandwich https://viajesfarias.com
