Non-traditional stable isotope signatures in geological matrices as a tool for interpreting environmental changes – a review

The development of new analytical techniques enabled the precise determination expanded set stable isotopes and provided insight into existing geological issues. This review outlines recent studies non-traditional isotope signatures in matrices, summarizing one place data for Ca, Mg, Sr, Li, Ni, Cr, Cu their application interpretation environmental processes. Although some them, such as ?44Ca ?26Mg, have been previously used to track changes seawater chemistry throughout history, report geochemical proxies post-depositional Similarly, isotopic strontium, radioactive chronology, ?7Li, tracing plate subduction crust/mantle material cycling, found a weathering patterns. use ?53Cr ? 65Cu signatures, on other hand, reflects fractionation under different redox conditions, whereas ?60Ni, due its co-precipitation with sulfide species Fe-Mn phases, is interpreting contributions sources. And while all these elements indicate certain conditions processes (e.g., processes, organic matter input, contribution sources, etc.), combining them more comprehensive investigated environment can be achieved.
