The calcite is porous and contains iron-rich calcite blebs interpreted to have resulted from fluid-mediated replacement of compositionally heterogeneous amphiboles. The siderite is …
Siderite amounts were found to vary in the range of 0–15 at.% for the iron-bearing minerals present. Ilmenite was also present in the bauxite of some of the …
Similarly, Sun et al. determined electrical conductivities of the olivine–ilmenite systems with various contents of ilmenite (V Ilm = 4, 7, 10, 11 and 15 vol%) and pure …
Ilmenite is a common and significant Fe-rich mineral phase in terrestrial and lunar rock, which has variable Cr contents. Herein, four natural ilmenites (RUS10, CZE2, SIN1, and …
Thus, we have demonstrated the ability of autotrophic thermophilic microbial consortium to perform a short cycle of iron minerals transformation: …
Primary ilmenite deposits are found in Canada, Norway, and China (Mudd and Jowitt 2016), whereas the Murray and Eucla Basins in Australia and the Pulmoddai …
In the absence of persulfate, pyrite (FeS 2) achieved a 1,1,2-TCA removal efficiency of 36% within 120 hours, whereas it was less than 20% for magnetite (Fe 3 O …
The microstructure of minerals and rocks can significantly alter reaction rates. This study focuses on identifying transport paths in low porosity rocks based on …
Iron in siderite is ultimately detrital: it can come from iron hydroxides or alteration of ilmenite. Siderite formation is facilitated by both mesophilic and …
