Transformation of Fe-Minerals in Hydromorphic Soils

Autor: A. T. Savichev, Yu. N. Vodyanitskii

Publikováno v: Moscow University Soil Science Bulletin. 75:1-7

Unstable Fe-minerals, which change the color of gley after the sample extraction from soil and make less pronounced the features of gleying in the dry season, are important in hydromorphic soils parallel to stable Fe-minerals conventionally detected

Life cannot emerge on a planet or moon without the appropriate electrochemical disequilibria and the minerals that mediate energy-dissipative processes. Here, it is argued that four minerals, olivine ([Mg>
Fe]2SiO4), bridgmanite ([Mg,Fe]SiO3),

International audience; Fougerite is a naturally occurring green rust, that is, a layered double hydroxide (LDH) containing iron (Fe). Fougerite was identified in natural settings such as hydromorphic soils. It is one of the few inorganic materials w

International audience; As there exists extended solid solutions between ferrous and magnesian silicates, experiments were conducted to check if ferrous and magnesian hydroxides can co-precipitate in a solid solution. Results show that no solid solut
