Iron 30 isotope
WebThe Zn isotope fingerprint is widely used as a proxy of various environmental geochemical processes, so it is crucial to determine which are the mechanisms responsible for isotopic fractionation. Iron (Fe) (hydr)oxides greatly control the cycling and fate and thus isotope fractionation factors of Zn in terrestrial environments. Here, Zn isotope fractionation and … WebAn isotope is a variation of an element where the atom contains the same number of protons and electrons, but differs in the number of neutrons it contains in the nucleus. For example this shows three isotopes of …
