Web5 jul. 2024 · Isotopic profiles across chemically zoned grains revealed homogenous B and Li isotopic compositions, demonstrating a strong advantage of their application as a provenance tool as opposed to major, minor or trace element signatures. WebThe two stable isotopes of Li, 6Li and 7Li, have the biggest relative mass difference (∼17%) of any iso-tope pair aside from hydrogen and deuterium. This leads to large variability in the isotopic composi-tions of Li at low temperature, with d7Li ranging from 56 in some sedimentary pore fluids (You et al.
The isotopes of lithium separate somewhat during a variety of geological processes, including mineral formation (chemical precipitation and ion exchange). Lithium ions replace magnesium or iron in certain octahedral locations in clays , and lithium-6 is sometimes preferred over lithium-7.
