What Lithoen records

Each claim states how it is known and cites its evidence.

EstablishedHexagonal

The Handbook of Mineralogy records the crystal data of hematite as hexagonal.

Evidence support: Supported by the cited evidence one source

Evidence: Mineral Data Publishing 2001 Institutional reference

Established5.26 g/cm3

The Handbook of Mineralogy gives a measured density for hematite of 5.26 g/cm3.

  • precision note: A reference value from a compiled data sheet, and for several species the midpoint or single figure of a published range.
  • method: Compiled from published measurements; Lithoen holds no measurement of its own.

Evidence support: Supported by the cited evidence one source

Evidence: Mineral Data Publishing 2001 Institutional reference

EstablishedFe2O3

Hematite is an accepted mineral species in the IMA List of Minerals, with the CNMNC-approved formula Fe2O3 and IMA status “approved”.

  • definition basis: IMA List of Minerals, September 2026 update, which is the authority on mineral species status.
  • precision note: An approved formula is an idealised composition; natural crystals of most species depart from it through substitution.

Evidence support: Supported by the cited evidence one source

Evidence: Commission on New Minerals, Nomenclature and Classification, International Mineralogical Association 2026 Primary authority
