WebStable Isotope Geochemistry is an introduction to the use of stable isotopes in the geosciences. It is subdivided into three parts: theoretical and experimental principles; fractionation processes of light and heavy elements; the natural variations of geologically important reservoirs. WebLithium isotopes fractionate substantially during a wide variety of natural processes, including mineral formation (chemical precipitation), metabolism, ion exchange (Li substitutes for Mg and Fe in octahedral sites in clay minerals, where 6 Li is preferential over 7 Li), hyperfiltration, and rock alteration (Morozova and Alferovskiy, 1974; Chan … Web21 uur geleden · PDF We present Li and B isotope data for muscovite, biotite, and feldspar + quartz separated from two-mica granite and biotite granite samples from...
