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

EstablishedMg2Si2O6

Enstatite is an accepted mineral species in the IMA List of Minerals, with the CNMNC-approved formula Mg2Si2O6 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
