Feroxyhyte is an oxide/hydroxide of iron, δ-FeO(OH). A number of species are dubbed iron(III oxide-hydroxide. These chemicals are Oxide - Hydroxides of Iron, and may occur in Anhydrous (( or It occurs in manganese-iron nodules on the Pacific Ocean floor. Manganese (ˈmæŋgəniːz is a Chemical element, designated by the symbol Mn. Iron (ˈаɪɚn is a Chemical element with the symbol Fe (ferrum and Atomic number 26 Polymetallic nodules, also called manganese nodules, are rock concretions on the Sea bottom formed of concentric layers of Iron and Manganese The Pacific Ocean is the largest of the Earth 's Oceanic divisions Forms under high pressure conditions and reverts to goethite on exposure to surface conditions. Goethite, named after the German Polymath Johann Wolfgang von Goethe, is an iron bearing oxide mineral found in soil and other low temperature environments Feroxyhyte crystallizes in the hexagonal system. Crystallization is the (natural or artificial process of formation of solid Crystals precipitating from a homogeneous --> identical Solution Regular hexagon The internal Angles of a regular hexagon (one where all sides and all angles are equal are all 120 ° and the hexagon has 720 degrees It forms as brown rounded to concretionary masses. Feroxyhyte is opaque, magnetic, has a yellow streak, and has a relative density of 4. 2.
