[QUOTE="user 4386, post: 414611, member: 4386"] Magnetite is SG 5.1, hematite 5.2, mahemite 4.9. Iron meteorites are 7 to 8 (not 3.8, that is more the SG of a stony meteorite). The SG that you give is possibly incorrect - I know of nothing that looks like that and has such a low SG. Limonite has SG 3.4 to 4 but does not look like that, does not have a red streak and is not magnetic. I suspect an intergrowth of magnetite and hematite, or maghemite. Try doing the SG again.
