| titleOfInvention | A common lead correction method based on laser micro-area in situ uranium and lead age determination of cassiterite samples |
| abstract | The invention discloses a common lead calibration method based on laser micro-area in-situ uranium-lead age determination of cassiterite samples. The sample target is placed in the sample cavity of the laser ablation cell; an excimer laser source is used and focused on the cassiterite sample on the sample target in a parallel light manner, so as to generate aerosol particles of the cassiterite sample; The aerosol particles of the cassiterite sample pass through the electric and magnetic fields in the magnetic inductively coupled plasma mass spectrometer to achieve double focusing of angle and velocity and reach the ion signal detection system; the cassiterite is detected by the ion signal detection system For the original lead-uranium ratio in the sample, the original lead-uranium ratio is corrected to obtain the corrected lead-uranium ratio; the corrected lead-uranium ratio is then used for lead-208 correction to calculate the uranium-lead age of the cassiterite sample. |
