Oxidation character of chlorite from Byrapur chromite deposit, India — A57Fe Mössbauer evaluation

Methane oxidation linked to chlorite dismutation

We examined the potential for CH4 oxidation to be coupled with oxygen derived from the dissimilatory reduction of perchlorate, chlorate, or via chlorite (ClO(-) 2) dismutation. Although dissimilatory reduction of ClO(-) 4 and ClO(-) 3 could be inferred from the accumulation of chloride ions either in spent media or in soil slurries prepared from exposed freshwater lake sediment, neither of thes...

A new type of pyroclastic deposit on the Moon containing Fe-spinel and chromite

[1] We present details of the identification of sites that show an absorption band at visible wavelengths and a strong 2 m band using the SELENE Spectral Profiler. All the sites exhibiting the visible feature are found on the regional dark mantle deposit (DMD) at Sinus Aestuum. All the instances of the visible feature show a strong 2 m band, suggestive of Feand Cr-rich spinels, which are differ...

Electron probe microanalysis and microscopy: Principles and applications in characterization of mineral inclusions in chromite from diamond deposit

New Data on the Mineralogy of Chromite from the Nuggihalli Schist Belt, Western Dharwar Craton, Karnataka, India: Petrogenetic Implications

The occurrence of rhythmic layering of chromite and host serpentinites in the deformed layered igneous complexes has been noticed in the Nuggihalli schist belt (NSB) in the western Dharwar craton, Karnataka, South India. For this study, the chromitite rock samples were collected from Jambur, Tagadur, Bhakatarhalli, Ranganbetta and Byrapur in the NSB. Petrography and ore microscopic studies on c...
