近日,中国地质大学资源学院和地质过程与矿产资源国家重点实验室李建威教授团队在国际地球化学顶级期刊发表题为《Hydrothermal reequilibration of igneous magnetite in altered granitic plutons and its implications formagnetite classification schemes: Insights fr...
New research challenges the prevailing theory that the unique nature of Earth’s iron was the result of how its core was formed billions of years ago.The study opens the door to competing theories abou...
Now spanning five simultaneous open-pit operations with exploration carried out through open pit benching, Carajás complex encompasses the world′s largest iron reserves. Open pit mining operations i...
Mineral dust deposition is suggested to be a significant atmospheric supply pathway of bioavailable iron (Fe) to Fe-depleted surface oceans.
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...
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...
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, 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...
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...
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...
The Estonian Devonian sediments consist of carbonate, siliciclastic, and mixed carbonate-siliciclastic deposits that have undergone extensive dolomitization. Chemical analysis of 165 samples and XRD m...
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...
Iron oxide-alloy equilibration experiments were conducted in H2 -CO2 gas mixtures at 1 atm and 1125–1240 °C using strips of Au74Pd26 (wt%) and produced Au-Pd-Fe alloys with 0.03–13 wt% iron. ...
We used sequential extractions to quantify different forms of particulate phosphorus (PP) in sediments along the salinity gradient of the Patuxent River estuary. About 50-90% of the PP was phosphate b...
