| titleOfInvention | A kind of method of the thorium lead age of the measure bastnaesite sample based on ion microprobe |
| abstract | The invention discloses a kind of method of the thorium lead age of the measure bastnaesite sample based on ion microprobe, including：Sample target will be made in bastnaesite sample and bastnaesite standard substance insertion epoxy resin, and the sample target is put into the sample cavity of ion microprobe；Oxygen gas plasma ion gun and the bastnaesite sample focused in directional light mode on the sample target are used, to produce the secondary ion of the bastnaesite sample；Make electric field and magnetic field that the secondary ion of the bastnaesite sample passes through in the ion microprobe, to realize angle and speed double focusing and reach ion signal detecting system；The primeval lead thorium ratio in the secondary ion of the bastnaesite sample is detected using the ion signal detecting system, the primeval lead thorium ratio is corrected with the lead thorium ratio after being corrected；The thorium lead age of the bastnaesite sample is calculated using the lead thorium ratio after correction. |
