  • Cr Release from Cr-Substituted Goethite during Aqueous Fe

    Iron (hydr)oxides such as lepidocrocite, goethite, and hematite are common secondary iron minerals in soils. Iron (hydr)oxides rarely occur in a chemically pure form, and usually contain structural trace metal admixtures in soils, especially in polluted soils with metallic contaminants [1,2,3].A number of trace metals, including Al(III), Ti(II), Cr(III), Mn(III), Ni(II), As(III), and Cu(II

  • Iron ore - Wikipedia

    Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO

  • High resolution hematite and goethite records from ODP

    Precipitation has a larger variability than temperature in tropical monsoon regions, thus it is an important climate variable. However, reconstructions of long-term rainfall histories are scarce because of the lack of reliable proxies. Here we document that iron oxide minerals, specifically the ratio of hematite to goethite (Hm/Gt), is a reasonable precipitation proxy.

  • Goethite Morphology and Composition in Banded Iron

    Goethite having reniform or wedge microstructures is cryptocrystalline in nature, poor in iron and contains 2–3.5% silica and <1–2% alumina. This probably represents the first formed goethite that precipitated from iron‐enriched fluid at low temperature.

  • High resolution hematite/goethite records from Chinese

    Feb 13, 2004· Analysis of hematite and goethite concentrations has been hindered by their low concentration, generally lower than the detection limit of an XRD, in soil and sediments. However, it has been shown [Deaton and Balsam, 1991] that reflectance spectroscopy can be used to analyze iron oxides at extremely low concentrations typical of natural conditions.
