Oxygen-isotope fractionation between aluminium hydroxides phases and water at <60�C: results of decade-long synthesis experiments
Oxygen-isotope data were obtained for synthetic aluminum-hydroxide phases precipitated over 65-125 mo and have been compared to results from similar experiments conducted for 3-56 mo. The Al(OH)3 polymorphs, gibbsite, nordstrandite, and bayerite, were synthesized, but gibbsite was dominant in most samples, and commonly the only phase present. Using pure gibbsite samples, the following oxygen-isotope fractionation factors, α(gibbsite-H(2)O), were obtained: 1.0167 ± 0.0003 (9 ± 1°C), 1.0147 ±...[Show more]
