| titleOfInvention | Ordinary lead correction method based on in situ cassiterite sample uranium-lead age determination based on laser micro-area |
| abstract | The invention discloses a common lead correction method based on laser micro-area in-situ cassiterite sample uranium-lead age determination, comprising: embedding cassiterite samples and cassiterite standard substances into epoxy resin to make sample targets, and The sample target is placed in the sample cavity of the laser ablation cell; an excimer laser source is used to focus on the cassiterite sample on the sample target in a parallel light mode, so as to generate aerosol particles of the cassiterite sample; The aerosol particles of the cassiterite sample pass through the electric field and magnetic field in the magnetic inductively coupled plasma mass spectrometer to achieve double focusing of angle and speed and reach the ion signal detection system; the cassiterite is detected by the ion signal detection system The original lead-uranium ratio in the sample is corrected to obtain the corrected lead-uranium ratio; the corrected lead-uranium ratio is used to perform lead-208 correction to calculate the uranium-lead age of the cassiterite sample. |
