Fission track dating
WebDec 6, 2012 · Fission track dating is based on the microscopic observation and counting of etchable tracks left by the spontaneous fission of uranium in minerals. Since its development in 1963 the method attracted a steadily growing interest from geologists and geochronologists throughout the world. Apart from its relative experimental ease the … WebMay 26, 2010 · More than a dozen other techniques also provide reliable age determinations: fission-track dating based on gradual accumulation of radiation damage, thermochronology based on the slow diffusion of atoms through rocks, methods that rely on surface weathering rates or even on the slow growth of lichens. These and other …

This book is focused on the basics of applying thermochronology to geological and tectonic problems, with the emphasis on fission-track thermochronology. It is conceived for relatively new practitioners to thermochronology, as well as scientists experienced in the various methods. The book is structured in two parts.
WebThis discordance means that the U-Th-Pb and fission track dating methods give wildly different dates for the zircon samples measured, most of which strongly diverge from the secular age expected for the Middle Cambrian rock. Similarly, the fission track dating for the Late Jurassic samples gives results that diverge from the expected geologic age.
