Oxygen-Isotope Fractionation between Aluminum-Hydroxide Phases and Water at <60C: Results of Decade-Long Synthesis Experiments
Aluminum Hydroxides Fractionation Factor Gibbsite Oxygen Isotope Synthesis
2011/12/6
Abstract: 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...
Oxygen Isotope Compositions of Mixed-Layer Serpentine-Chlorite and Illite-Smectite in the Tuscaloosa Formation (U.S. Gulf Coast): Implications for Pore Fluids and Mineralogic Reactions
Diagenesis Illite-Smectite Oxygen Isotopes Sandstone Serpentine-Chlorite Tuscaloosa Formation
2011/12/8
Abstract: Oxygen isotopic compositions were determined for coexisting mixed-layer serpentine-chlorite (Sp-Ch) and illite-smectite (I-S) from 5 Tuscaloosa Formation sandstone cores sampled between 1937...
Oxygen Isotope Measurements of Albite-Quartz-Zeolite Mineral Assemblages, Hokonui Hills, Southland, New Zealand
Albite Diagenesis Formation temperature Heulandite Laumontite Oxygen isotopes Quartz Stilbite Zeolites
2012/1/6
The oxygen isotopes of albite, quartz, and zeolites from the Hokonui Hills, New Zealand, constrain crystallization temperatures and the type of pore fluids present during diagenesis. A section of alte...
Oxygen Isotope Changes during Mica Alteration
Mica Oxygen isotopes Potassium Recrystallization Saponite Weathering
2012/2/1
Oxygen isotope analyses (δO18) of micas that were artificially depleted in K+ indicate little or no isotope exchange during the transformation. The oxidation of iron in K-depleted, iron-rich micas by ...
