WebJul 25, 2016 · Abstract The upper continental crust (UCC) is an important reservoir of Ba within the Earth. We report high precision (≤±0.05‰, 2SD) Ba isotopic data for 71 samples (including granites, granodiorites, loess, glacial diamictites, and river sediments) to constrain the Ba isotopic composition of the UCC. I-type granites from the Fogang batholith, … WebWhen carbonates are reacted with othophosphoric acid, they produce a CO 2 gas in isotopic equilibrium (but with a constant offset linked to acid temperature) with the original carbonate. The field of clumped isotopes is concerned with measuring an isotopologue of CO 2 gas with a mass of 47, i.e. where the two “heavy” rare isotopes (13 C and 18 O) …

WebIn particular, if the Pb isotopic diversity in Mangaia MIs is caused by crustal assimilation processes, it is expected that Pb-isotopic compositions will correlate with tracers of assimilation (e.g., high Cl and B, Sr isotopes), whereas this is unlikely to be the case if the isotopic diversity reflects diverse mantle sources beneath Mangaia.
