Iron-Oxide Concretions and Nodules, 1 Some Meteorite ...

Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people’s attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.
