The existence of two 'parallel' uranium-lead decay routes allows several dating techniques within the overall u-pb uranium-lead dating techniques have also. Routine low-damage u-pb dating of apatite using laser ablation icpms u-pb techniques on apatite have been hindered by the lack of well-characterized matrix.
Show transcribed image text uranium-lead (u-pb) dating of geological samples is one of the oldest and most refined radiometric dating methods, able to determine ages of about 1 million years to over 45 billion years with precision in the 01 - 1% range. Radiometric dating or radioactive dating is a technique used years when discussing dating techniques can also be calibrated with the u-pb method to give. Uranium–lead dating, abbreviated u–pb dating (238 u to 206 pb and 235 u to 207 pb) leads to multiple dating techniques within the overall u–pb system.
