  • Meteorite Identification: Have you found a space rock?

    Iron is heavy and most meteorites feel much heavier in the hand than an ordinary earth rock should. A softball-sized iron meteorite will likely weigh five or six pounds, making it seem unnaturally dense. Imagine holding a steel ball bearing as big as a grapefruit and you'll get the idea.

    2017-04-24· The thin crust looks black, but years after the meteorite has fallen to Earth, the crust begins to wear away. Check the inside of the rock if it is exposed. A bumpy, irregular feature known as a regmaglypt may appear on the surface or interior of some meteorites. Iron meteorites often have these regmaglypts all over their surface.

  • Meteorite Home Tests

    There are three classes of meteorites: stony, iron, and stony-iron. A meteorite is heavier than an ordinary rock and will be attracted to a magnet. The condition of a meteorite can range from fresh to very weathered. Fresh meteorites have fusion crust, an aerodynamic shape and possibly thumbprints (regmaglypts). Weathered meteorites may be more

    2017-04-24· Meteorites are heavy due to their high iron content, so they tend to feel heavier than most Earth rocks of the same size. Magnetite is made up of iron oxide, making it opaque and metallic, much like a meteorite could appear; some other meteorites, however, can be brown or gray. Most meteorites contain an iron and nickel alloy, while terrestrial

    Iron Meteorites. When I give lectures and slideshows about meteorites to rock and mineral societies, museums, and schools, I always enjoy commencing the presentation by passing around a softball-sized iron meteorite. Most people have never held a space rock in their hands and when someone does pick up an iron meteorite for the first time their

  • Meteorite Identification The Meteorite Exchange, Inc.

    If a magnet will stick to your rock or a magnet will pull the rock when it is hung from a string that may mean there is iron metal in the suspect rock. You will want to grind a little spot as discussed above and see if there is metal. But many rocks on the Earth that are not meteorites contain iron in chemical forms that are magnet responsive

  • Meteoric iron Wikipedia

    Meteoric iron, sometimes meteoritic iron, is a native metal and early-universe protoplanetary-disk remnant found in meteorites and made from the elements iron and nickel mainly in the form of the mineral phases kamacite and taenite.Meteoric iron makes up the bulk of iron meteorites but is also found in other meteorites. Apart from minor amounts of telluric iron, meteoric iron is the only

    2013-12-07· True iron-nickel meteorites will have a strong attraction, so that would likely rule it out. The rust definitely sounds on target, but another strange thing is that you describe it as being very light, when in fact iron-nickel meteorites will be heavy. To test conductivity, use an ohmmeter.

  • meteorite Definition, Types, Identification, & Facts

    A better approach to finding meteorites than searching places with few rocks, however, is to search places where they can accumulate over time—i.e., where the surface is quite old and rates of weathering are low. Because meteorites contain minerals, such as iron metal, that are easily weathered, they do not normally last long on Earth’s

  • Comparing Meteorites to Earth Rocks

    They also contain minor amounts of metals, particularly nickel and iron alloys. Stony meteorites account for 95% of all meteoritic material. Stony-iron meteorites contain a mixture of silicate minerals and nickel-iron alloy. Stony meteorites are similar to igneous Earth rocks like basalt. Iron meteorites probably resemble the material in the

    Many meteorites (typically iron meteorites) are quite dense and feel heavier than most Earth rocks. Test the specimen's magnetism using a standard fridge magnet. Nearly all meteorites contain iron-nickel metal and attract magnets easily. Check for holes or bubbles in the specimen. A true meteorite will not have any holes or bubbles at all. If
