Radiometric dating uncertainty

Therefore, the most precise dating method for these meteorites is the Pb–Pb method, which allows a correction for common Pb.

The U/Pb ratio was so low that no radiogenic decay was detected in the isotopic composition.Hence the best age for the original formation of the solar system is 4567.7 My.This date also represents the time of initiation of planetary accretion.Chondrules and calcium–aluminium-rich inclusions (CAIs) are spherical particles that make up chondritic meteorites and are believed to be the oldest objects in the solar system.Hence precise dating of these objects is important to constrain the early evolution of the solar system and the age of the earth.
