Definition fission track dating
We provide science about the natural hazards that threaten lives and livelihoods; the water, energy, minerals, and other natural resources we rely on; the health of our ecosystems and environment; and the impacts of climate and land-use change.
Our scientists develop new methods and tools to supply timely, relevant, and useful information about the Earth and its processes.
If the rock is today at the surface, this process gives the exhumation rate of the rock.
Price and Walker  also discovered fossil tracks of U spontaneous fission in muscovite mica and invented the technique of fission track dating. [5, 6] recognized that thermal fading of tracks follows the Arrhenius equation, and later many other scientists confirmed its correctness .
Fission track method has been widely used, and up to now, it is still one of basic techniques for nuclear science dating. The difference between the max and min values was large as 18.4%. (1) to calculate the age (order of 106a), they showed a difference of 18% or so.
The zircon grains were mounted in glass slides, heated and covered by FEP Teflon sheets.
Their external prismatic surfaces were ground and polished.
