Shell organic matrix isotopes and water isotopes Unlike the carbonates48, the δ18O values of the SOM and IOM differed significantly from respective water δ18O signatures at each site (Fig.4). The SOM δ18O values showed a weak positive correlation with the δ18O values of water at Caras...
This is in contrast to the range of stable isotopes of even Z, which includes nuclei of both even and odd N, although the former outnumber the latter. Tin (Z = 50), for example, has 7 stable even-even isotopes and only 3 even-odd ones. The greater number of stable nuclei with ...
Proton-Rich IsotopesNucleosynthesisHeavy ElementsThe beginning of our universe as we know and interpret it was the Big Bang. About 14 billion years ago, the entire universe started to expand. This expansion was accompanied by a global cool down of all matter and radiation forming the universe. ...
Yuri Dublyansky4, Philippe Audra5, Victor Polyak6, Yemane Asmerom6 & László Palcsu1 Alteration of conventional carbonate stable isotopes (δ18O, δ13C) in cave walls has been shown to be a useful tool to identify cave formation driven by deep-seated processes, i.e., ...
34. This system can accurately measure stable isotopes in CaCO3samples for amounts as low as 0.2 µg. Carbonate samples were reacted with 104% H3PO4at 25 °C. The evolved CO2gas was first purified in a stainless-steel vacuum line and then in a helium-purged purification line. The ...
