Micro-Raman spectroscopy and SEM/EDX applied to improve the zircon fission track method used for dating geological formations
(John Wiley & Sons Ltd, 2009-01-01)
The zircon mineral is widely studied in geochronology. In the case of the fission track method (FTM), the age is determined by the density of fission tracks at the zircon surface, which can be observed with an optical ...

Uranium-bearing francolites present in organic-rich limestones of NW Greece: a preliminary study using synchrotron radiation and fission track techniques
(Springer, 2017-01-01)
Synchrotron radiation techniques (mu-XRF and mu-XANES) were applied to the study of organic-rich phosphatized limestones of NW Greece (Epirus). The results revealed uranium accumulation in areas of the material containing, ...
