Radiogenic isotope dating
Isochron dating can be further separated into mineral isochron dating and whole rock isochron dating; both techniques are applied frequently to date terrestrial and also extraterrestrial rocks (meteorites).
Therefore, the uranium isotope ratio serves as some kind of natural indicator of water of a certain water-bearing complex.This fact makes it possible to determine patterns of natural water filtration; to distinguish the rock of the water-bearing complex, to construct models of groundwater circulation, to establish the mixing proportions of waters of different complexes and to examine the interrelations between waters of different complexes.Covering radiogenic, radioactive, and stable isotopes, this comprehensive text contains five sections that present fundamentals of atomic physics; dating methods for terrestrial and extraterrestrial rocks by means of radiogenic isotopes; geochemistry of radiogenic isotopes; dating by means of U, Th-series and cosmogenic radionuclides; and the fractionation of the stable isotopes of H, C, N, O, and S, as well as Li, B, Si, and Cl.

Isochron dating is a common technique of radiometric dating and is applied to date certain events, such as crystallization, metamorphism, shock events, and differentiation of precursor melts, in the history of rocks.
Ra) in natural waters are discussed in this chapter.
Methods of dating surface waters, groundwaters, closed reservoirs and bottom sediments are analysed.
The values of the radiogenic isotopes in waters are practically independent of chemical factors.
It is mainly determined by the uranium distribution in rocks of a water-bearing complex.
