Effect of Oxygen Fugacity on Fassaitic Pyroxene [PDF]
, 1983 Stability of fassaitic pyroxene in the system CaMgSi2O6-CaFeAlSiO6-CaAl2SiO6-CaTiAl2O6 is discussed on the basis of published data. In the system CaMgSi2O6-CaFeAlSiO6 the stability field of clinopyroxene decreases with an increase in CaFeAlSiO6 content ...

Diffuse reflectance spectra for heated samples of an H5 chondrite: Importance of oxygen fugacity at heating [PDF]
, 2000 P(論文)We obtained (biconical) diffuse reflectance spectra of the Nuevo Mercurio (H5) ordinary chondrite in the 200-2500 nm wavelength region. The samples were heated in the temperature range of 800-1200℃ at constant oxygen fugacities at one log unit below

Sensibility of Tourmaline Chemistry to Granitic Magma Composition and Oxygen Fugacity
, 2022 Extensive granitic magmatism is a dominant feature of the Central Iberian Zone (CIZ) of the Variscan Orogen. For the most part, these are S-type peraluminous granitic rocks exhibiting variable degrees of evolution and compositions ranging from granodiorites, through mon zogranites and granites to leucogranites, bearing either biotite and muscovite, or ...

Atmospheric Chemistry of Secondary and Hybrid Atmospheres of Super Earths and Sub-Neptunes
The Astrophysical JournalThe atmospheres of small exoplanets likely derive from a combination of geochemical outgassing and primordial gases left over from formation. Secondary atmospheres, such as those of Earth, Mars, and Venus, are sourced by outgassing. Persistent outgassing

Journal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 7775-7783, October 2026.Abstract BACKGROUND Cocoa (Theobroma cacao L.) from the Brazilian Amazon plays an important role in national production. While most cocoa is cultivated in upland systems, floodplain ecosystems represent a traditional and distinct production environment that may influence bean composition and quality.
