  • Chromite - iron magnesium chromium oxide
  • Daubreelite - iron(II) chromium sulfide
  • Diamond and lonsdaleite - carbon
  • Graphite - carbon
  • Haxonite - iron nickel carbide
  • Kamacite iron nickel alloy - the most common component.
  • base metal sulfides
  • Schreibersite - iron nickel phosphide
  • Taenite iron nickel alloy
  • Troilite a variety of the iron sulfide mineral pyrrhotite. The troilite in this sample is used as the standard reference for sulfur isotope ratios.

Famous quotes containing the word composition:

    The naive notion that a mother naturally acquires the complex skills of childrearing simply because she has given birth now seems as absurd to me as enrolling in a nine-month class in composition and imagining that at the end of the course you are now prepared to begin writing War and Peace.
    Mary Kay Blakely (20th century)
