Pb-pb dating – A Color Story

Uranium–lead dating, abbreviated U–Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million years to over billion years ago with routine precisions in the –1 percent range.

The rocks and minerals used for U-Pb dating are usually collected from surface outcrops where they have been exposed to chemical weathering. Therefore, the discordance of model U-Pb ages may also be due to disturbances of the daughter-to-parent ratios caused by chemical weathering.

Along with stratigraphic assumptions, the U-Pb and Th-Pb dating methods have been regarded as the gold standard for “deep-time” dating. Very few in the geochronology field would dare question the results of these dating methods, and therefore, by consensus, they are considered as scientific fact within the secular scientific community.

Jul 16,  · Pb Pb Dating. The first attempt to date the CB a Gujba chondrites was reported by Krot et al. () where they applied the absolute Pb-Pb dating method on silicate chondrules. They picked compositionally distinct fractions from three chondrules that were combined and regressed to define an average Pb isotopic composition of all fractions.

The Age of the Earth - Lead Isotopes as a Current Scientific Clock: Paul Bechard

Lead–lead dating is a method for dating geological samples, normally based on 'whole-rock' samples of material such as granite. For most dating requirements it has been superseded by uranium–lead dating (U–Pb dating), but in certain specialized situations (such as dating meteorites and the age of the Earth) it is more important than U–Pb dating.

Radiometric Dating

U-Pb radioisotope dating is now the absolute dating method of first choice among geochronologists, especially using the mineral zircon. A variety of analytical instruments have also now been developed using different micro-sampling techniques coupled with mass spectrometers, thus enabling wide usage of U-Pb radioisotope dating.
