THE METEORITE MARKET

Index of Iron Meteorites for Sale


IRON METEORITES were once surmised to come from the cores of asteroids, but recent studies suggest that while some may be from asteroid cores, others may be formed in concentrations of iron on asteroid surfaces. This is an evolving area of knowledge. Isotope studies suggest that certain classifications of irons may be associated with certain clans of stony meteorites. You can see one proposed scheme here. The crystal patters associated with iron meteorites is similarly being reconsidered. Patterns may be from cooling or post-cooling processes.

There are two systems of classification of iron meteorites; structural classification and chemical classification. See our TYPE TABLE for more information.

The STRUCTURAL CLASSIFICATION system relies on the nature and sizes of the crystals of iron nickel metal. There are three basic structural classes;

  • hexahedrites (<5% nickel, almost pure kamacite. Etched faces show Neumann lines)
  • octahedrites (intermediate nickel with plates of kamacite and taenite interwoven to form a Widmanstatten pattern on etched faces) The octahedrite group is further divided by crystal size into subgroups: finest (Off), fine (Of), medium (Om), coarse (Og), and coarsest (Ogg).
  • ataxites (usually >13% nickel, almost pure taenite) these show no structure because of chemical or physical reasons.

The structural classification system was devised by a museum curator and is popular with collectors.

Scientists are more likely to use the CHEMICAL CLASSIFICATION system. Chemical classification relies on the ratios of trace elements in iron meteorites. To see a list of the chemical types, look at our type table. For more about the details of this system, see Field Guide to Meteors and Meteorites, Rocks from Space or Meteorites and Their Parent Planets.

If something is list as "temporarily out of stock" that probably means we have more of it that we need to prepare for sale. Check the list on the front page for the most recent availability.

    About Meteorite Names

    Meteorites take the name of the place where they fell or were found. For example, the Canyon Diablo meteorite was found near Canyon Diablo, Arizona, the Allende meteorite was found near the town of Allende in Mexico, the Sikhote-Alin meteorite fell in the Sikhote-Alin mountains of Russia, and so on.

    Iron is something most unusual . . .

    Iron meteorites are made of native iron metal mixed with a small amount of nickel. Outside of meteorites and man-made iron, native iron is exceedingly rare. Early peoples found meteorite iron to be useful for knives and tools.

    Iron Meteorites Are Very Rare

    Iron meteorites are extremely rare. Of all of the meteorites that fall on the earth, scientists estimate that only about five percent are Iron Meteorites. The Handbook of Iron Meteorites lists only about 275 iron meteorite finds for the United States--one of the most intensely searched countries in the world. Because they are so different from other Earth-rocks, a higher percentage are found.
