Isotopic Mineralogy,e. Many of them are absolutely stable in accordance with the law of conservation of energy, as the energy potential of the system originated by their radioactive decay would exceed that of the initial system. For instance, α-decay of .O or fission of .Si into .O and .C are absolutely prohibited. Ano
