Rayleigh fractionation
WebFine-scale analyses of δ34 Spyrite patterns can be used to extract environmental information from ancient microbial mats and aid in the interpretation of bulk ε34 S records and closed-system Rayleigh fractionation effects. WebMar 29, 2024 · It should be noted that ice wedges are subject to large internal isotopic variations, often with low signal-to-noise ratios within horizontal profiles sampled at the same depth within a single ice wedge. 28 Further, sampling depth dependencies due to Rayleigh fractionation during snowmelt freezing and ice plugging, noncentric contraction …
