Fission track dating phosphate minerals thermochronology apatite
TPSZ was thus affected by the intense deformation in the area adjoining this shear zone.
With this background of geological events, it was thought that fission track dating on cogenetic minerals might help unravel the uplift history of syenite rocks of the Sushina hill.
The samples were irradiated in the thermal facilities of FRMII at Garching, Germany together with dosimeter glass IRMM-540R (15 ppm).
The samples were prepared using standard separation, grinding and polishing techniques .
All the samples were prepared for the external detector method.
AFT mounts were etched with 70% HNO at room temperature for 30 s. Zircons were etched in KOH-Na OH eutectic etchant [36-39] at 215°C on Spinot digital hot plate for ∼8 hrs.
