Feroxyhyte is opaque magnetic has a yellow streak and has a relative density of 4.2.It occurs in manganese-iron nodules on the Atlantic and Pacific Ocean floors. It is also found in the Baltic White and Kara Seas. Forms under high pressure conditions and reverts to goethite on exposure to surface conditions.
