Definition of haematite in English: haematite(US hematite) noun ˈhiːmətʌɪtˈhiməˌtaɪt A reddish-black mineral consisting of ferric oxide. It is an important ore of iron. Example sentencesExamples - Minor hematite gives some specimens a red color.
- Carriers include the iron oxides magnetite and hematite.
- The red sandstone is made up of quartz grains coated with hematite, an iron oxide mineral that gives the stone a red colour.
- The fluids that precipitated the veins were a likely source for some of the iron that formed the hematite.
- Among the simple oxides, only anatase and hematite have been found to date.
- The ironstone is locally represented by hematite matrix-supported vein quartz breccia.
- The third potential way the hematite could have formed is by oxidation of a mineral called magnetite in basalt and lavas.
- Those theories include that the haematite may have formed in a long-lasting lake or in a volcanic environment.
- Some of the material contained micaceous masses of specular hematite associated with quartz, epidote, and numerous veinlets of calcite.
- Most, if not all, of these mines have likely produced specimen-quality hematite, goethite, and perhaps other minerals.
- Like hematite, some goethite is pseudomorphic after a rhombohedral carbonate mineral.
- This colour change occurs over only a few metres on the ground and is probably related to the reduction of hematite to magnetite.
- Impressive blades and masses of lustrous micaceous hematite occur in localized quartz veins, and reniform goethite is found in the walls.
- Even if the hematite's origin remains ambiguous, trace amounts of other minerals could serve as additional markers of past water.
- This was a steely gray specimen of the mineral hematite which, like many other stones, has a tradition of healing and additional magical influences.
- The lakebed is believed to contain hematite, a crystalline iron compound usually formed in the presence of water.
- The assemblage present included quartz, chalcopyrite, pyrite, sphalerite, magnetite, and hematite.
- Some samples have hematite in the calcite veins.
- Both areas were selected because they have an ancient layer of hematite, an iron oxide mineral that on Earth almost always forms in an aqueous environment.
- Some hematite replacement erases all traces of the original mineralogy.
Origin Late Middle English: via Latin from Greek haimatitēs (lithos) 'blood-like (stone)', from haima, haimat- 'blood'.
