Radiogenic Isotopes in an Exocontact Zone of a Magmatic Body,e systems. The measured isotope ratios are usually shown in data tables and graphs with standard deviations of 5 or 6 true ciphers. Often, the measured results are considered as an ultimate step for an isotope study. The precise data presume however a satisfactory description of natural geologic pro

Diffusion in a Laplace Regime,adiogenic isotopes in rocks and K–Ar isotope system in the Laplace diffusion losses. It is important to define boundary conditions of such an isotope system. As diffusion losses increase, the rate of accumulation of daughter substance approaches zero (∂./∂.=0) and the Fick equation turns to the Lapl
