APAKAH MAKSUD GOETHITE dalam CORSICA?
Goethite
Goethite (FeO (OH)), yang dinamakan sempena polymath Jerman dan penyair Johann Wolfgang von Goethe (1749-1832), yang mengandungi mineral hidroksida galian kumpulan diaspor, ditemui di tanah dan lain-lain yang rendah -temperature persekitaran. Goethite telah terkenal sejak zaman prasejarah untuk kegunaannya sebagai pigmen (ocher). Bukti telah didapati penggunaannya dalam sampel pigmen cat yang diambil dari gua-gua Lascaux di Perancis. Ini pertama kali diterangkan pada tahun 1806 untuk kejadian di Tambang Hollertszug, Dermbach, Herdorf, Siegerland, Rhineland-Palatinate, Jerman. Pada tahun 2003, nanoparticulate goethite authigenic ditunjukkan sebagai oxyhydroxide besi diagenetik yang paling biasa di kedua-dua sedimen marin dan tasik.
Definisi goethite dalam kamus Corsica
Takrif goethite dalam kamus adalah mineral hitam, coklat, atau kuning yang terdiri daripada oksida besi terhidrasi dalam bentuk kristal ortorombik atau massa berserabut. Formula: FeO.

Characterization of Corrosion Products on Steel Surfaces
The protective rust layer is believed to possess the structure of α-(Fe1−x,Crx)
OOH, which is called Cr-goethite. The corrosion rate of weathering steel
decreases as the X-ray amorphous substance forms and matures into the
goethite phase.
