Apatite Fission Track analysis (AFTA) was used in order to understand the time-low-temperature evolution of crystalline rocks from studied area.
This concordance of apatite fission track (AFT), zircon fission track (ZFT) and K-Ar biotite ages, therefore, robustly suggests that they all document the age of emplacement of the Sillai Patti carbonatite complex.
An international research team analysed rocks collected from the Yingxiu-Beichuan fault in Sichuan, China, using fission track dating--the analysis of decaying uranium in minerals.
They also used the fission track dating, an analysis of tracks or trails left by decaying uranium in minerals in apatite and zircon.
