5 The U-Pb system

U–Th–Pb apatite dating by ICPMS has potential to be combined with other analytical methods for provenance work. Analytical techniques that could in principle be undertaken in conjunction with U–Th–Pb dating include fission track, (U–Th)/He or Nd isotopic analysis.

Three independent ages may be obtained in the U-Th-Pb system: Pb/ U, Pb/ U or Pb/ Pb, and Pb/ Th. Emphasis has been placed on U-Pb dating because the value U/ U is a physical constant that permits internal treatment of the data not found in any other dating system. This treatment helps to eliminate the assumption that the phase being dated has remained .

Uranium–lead dating - Wikipedia

Uranium-Thorium dating is based on the detection by mass spectrometry of both the parent ( U) and daughter ( Th) products of decay, through the emission of an alpha particle. The decay of Uranium to Thorium is part of the much longer decay series begining in U and ending in Pb.

Of the various methods, uranium-thorium-lead (U-Th-Pb) was the first used and it is still widely employed today, particularly when zircons are present in the rocks to be dated. But the method does not always give the “expected” results, leading to fundamental questions about its validity.

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 [2] from about 1 million years to over billion years ago with routine precisions in the –1 percent range.
