resulting in the enhancement of SOC decomposition (Hu et al.2021). Fe minerals can also promote the interspecies electron transfer between microbes and sequentially enhance the biodegradation of SOC and methane emission
While there were similarities in the latitudinal profiles of Fe-Al oxides and SOC, differences were observed in the latitudinal profiles of various forms of the oxide minerals. The global distribution map of Fe-Al oxides (Supplementary Figs.S3and4) revealed distinct latitudinal variations among the ...

This paper describes a preliminary study that attempts to determine the oxidation state of Fe (Fe3+/∑Fe) with the electron microprobe (EMP) by measuring the self-absorption induced shift of the Fe L α peak emitted from minerals and glasses. In transition metals of the first row, the L ...
The accessory Fe-Ti oxide minerals in the gabbro-noritic rocks reveal a re-equilibration temperature of 498 °C with corresponding log fO2 of 27.1. The sulfide minerals (mainly pyrite) are of two Declaration of Competing Interest The authors declare that they have no known competing financial ...
delayed the Fe reduction process, which subsequently delayed Cd immobilization. Mobilization of Cd uponsoil drainagewas caused by a decrease in soil pH resulting in the release of Cd from secondary minerals. 土壤淹排水过程...
The Ula Nui Fe oxide spectrum is compared with spectra collected from reference Fe oxide minerals goethite, 6-line ferrihydrite and 2-line ferrihydrite (reference spectra courtesy of Scott Fendorf). The regions of the Fe EXAFS spectra indicated by arrows (at 5.5 and 7.5 A˚ À1) highlight...
