One of most important works in this technique is how to accurately determine Sm is a very advanced one.

Instead, helium isotope, as a gas, makes itself difficult to measure.

A typical thermochronological study will involve the dates of a number of rock samples from different areas in a region, often from a vertical transect along a steep canyon, cliff face, or slope. With some knowledge of the subsurface thermal structure, these dates are translated into depths and times at which that particular sample was at the mineral's closure temperature.

Our scientists develop new methods and tools to supply timely, relevant, and useful information about the Earth and its processes.

Reconstruction of thermal event history is a good quality of the fission track method that can indicate the variety relationship between temperature and time for the thermal event [1].

Silk and Barnes [2] first recognized track fading when they observed fission fragment tracks in muscovite mica under transmission electron microscope.
