Beyond the geological implications of these results, U-Pb LA-ICP-MS dating of apatite appears to represent an ideal tool to date small size mafic intrusions.

This study presents apatite LA-ICP-MS U-Pb age and trace elements concentrations data from different granite types from the Tatra Mountains, Poland.5.1) Mc Clure Mountain apatite fractionation standard (MMap) The Cambrian Mc Clure Mountain syenite of Colorado is well known as the source of the widely used Ar hornblende standard MMhb and apatite from this rock has a published U-Pb TIMS age of 523.5 Ma.Typical self-normalized concordia age uncertainty for 10-12 spots during a typical sample run is between 1.2-2.0% at the 2 sigma level.
