The burial shroud had been colored with a dye containing goethite, which in its original unfaded state would have made the shroud look like it was woven from gold. Historians speculate that the legend of King Midas' golden touch might have originated from Phrygian royalty wearing clothes made from such golden-colored textiles. 470:, the analogous aluminium oxide-hydroxide mineral. Oxygen and hydroxide ions form a hexagonal close-packed structure, with iron ions filling octahedral sites between the anions. The sites filled by iron ions form paired chains running the length of the crystal, with the two chains in each pair joined by hydroxide ions. 269: 535:
iron oxyhydroxide in both marine and lake sediments. The formation of goethite is marked by the oxidation state change of Fe (ferrous) to Fe (ferric), which allows for goethite to exist at surface conditions. Because of this oxidation state change, goethite is commonly seen as a
