The O2-H⋯O1 donor-acceptor distance in goethite is significantly longer than that in diaspore or groutite, indicating that the hydrogen bonding in goethite is the weakest of the three minerals. Analysis of refinement data for the three isostructural compounds reveals rigid-body thermal motion behavior of the octahedral groups.

Goethite

Goethite ( α -FeOOH) Due to its high stability, goethite is the most ubiquitous Fe oxide mineral in soils. In the absence of hematite, its yellowish color is responsible for the yellowish-brown hue of many soils (7.4 YR–3.5 Y). Goethite formation is favored by slow hydrolysis of Fe 3+ hydroxy cations at low temperature.

Goethite Mineral

Goethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of veins of iron minerals, such as pyrite, magnetite and siderite. Goethite may occur with these minerals in the gossan, or iron hat, which is the weathered capping of an iron ore deposit.

What is the other name of limonite?

Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle ironstone") but is more typically massive. Why is it called goethite?

Synthesis, characterization and application of goethite mineral

01.09.2013FT-IR spectra of the synthesized goethite mineral show very broad IR band at 3174.1 cm −1, which can be attributed to the stretching vibration of surface H 2 O molecules.The characteristic sharp bands at 798.0 cm −1 and 892.4 cm −1 can be assigned to the Fe–O–OH bending vibration in α-FeOOH. The 656.7 cm −1 band is ascribed to

The studied temperatures ranged between 25 and 800 C. Major differences were found for gibbsite, goethite and kaolinite contents due to dehydration. PLS-2 analysis presented better results than HCA as it provided information concerning the two features of the investigated soils, the collection site and the temperature.

Minerals Abstract Surface defects have been shown to facilitate electron transfer between Fe (II) and goethite (α-FeOOH) in abiotic systems. It is unclear, however, whether defects also facilitate microbial goethite reduction in anoxic environments where electron transfer between cells and Fe (III) minerals is the limiting factor.
