Glauconite Iron Mossbauer spectroscopy Oxidized zone Pyrite Reduced zone Soil
2011/11/30
Abstract: Glauconite from the oxidized and reduced zones of soil-geologic columns at two Coastal Plain sites, one in Maryland and one in New Jersey, was examined by M鰏sbauer spectroscopy. The data ind...
Identification of Iron Rusts on Rail by X-Ray Diffraction and Vibrational Analysis
Corrugation Rail Railway Raman Scattering Submarine Tunnel Vibrational Spectroscopy X-Ray Diffraction (XRD)
2011/12/16
A periodical unevenness of the running surface of rails is formed on ascending slope of submarine railway tunnel. One of the causes has been concluded due to the combination of a low friction and whee...
Optimization of Stope Structure Parameters in E’xi Iron Mine Based on Rock Stress Analysis
Numerical Simulation with the Finite Element Method Rock Mechanic Stope Structure Parameters Optimization Stress Analysis Underground Mining
2011/12/20
Underground mining causes the redistribution of surrounding rock stress. The value of rock stress is one of the important factors that should be considered when stope structure size is designed. E’xi ...
Effects of pH, ionic strength, temperature, and humic acid on Eu(III) sorption onto iron oxides
Iron oxides Eu(III) Sorption HA Temperature
2011/11/10
Effects of pH, Eu(III) concentration, ionic strength, temperature and humic acid (HA) on Eu(III) sorption to iron oxides were investigated in detail. The sorption of Eu(III) to iron oxides was signifi...

2011/11/22
In this article, we have carried out the Ni based self fluxing alloy powder and studied the effect on the laser alloying of 45steel layer which contains different weight percentage of nano-SiC powders...
Desferrioxamine-B adsorption to and iron dissolution from palygorskite and sepiolite
DFOB Siderophore Fibrous clays Weathering Kinetic Isotherm
2011/11/4
Dissolution weathering of minerals can be greatly affected by the presence of siderophores and their adsorption in soil environments. In this research, adsorption equilibria and kinetics of desferriox...
Microbial biomineralization of iron seepage water: Implication for the iron ores formation in intertidal zone of Zhoushan Archipelago, East China Sea
ancient wood layer seepage water biomineralization iron ores intertidal zone
2017/8/9
The biogeochemcical reactions responsible for fossilized minerals preservation in ancient geological conditions are very often debatable, because little is known about the in situ processes at geo-his...
