Meteorite classification. In meteoritics, a meteorite classification system attempts to group similar meteorites and allows scientists to communicate with a standardized terminology when discussing them. Meteorites are classified according to a variety of characteristics, especially mineralogical, petrological, chemical, and isotopic properties.
Scientific research in meteoritics includes the collection, identification, and classification of meteorites and the analysis of samples taken from them in a laboratory. Typical analyses include investigation of the minerals that make up the meteorite, their relative locations, orientations, and chemical compositions; analysis of isotope ratios ...
Meteorite. The 60- tonne, 2.7 m-long (8.9 ft) Hoba meteorite in Namibia is the largest known intact meteorite. [1] A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the ...
The Murchison meteorite is a meteorite that fell in Australia in 1969 near Murchison, Victoria. It belongs to the carbonaceous chondrite class, a group of meteorites rich in organic compounds. Due to its mass (over 100 kg or 220 lb) and the fact that it was an observed fall, the Murchison meteorite is one of the most studied of all meteorites. [2]
That’s over $15,000 per pound! Pieces of Mars rock can command similar prices, with a 4.25-pound piece selling for $63,000, approximately $15,000 per pound. Meteorites from the Moon are even ...
A laboratory analysis by a qualified meteoriticist, however, is the only way to tell if a potential meteorite is genuine. If the meteorite is of the iron or stony iron variety a magnet (usually mounted at the end of a stick) will pick it up from the soil surface or a metal detector will often detect it through many inches of soil.
Iron meteorites, also called siderites or ferrous meteorites, are a type of meteorite that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Most iron meteorites originate from cores of planetesimals, with the exception of the IIE iron meteorite group
A man in Michigan recently learned that what he thought was large rock is actually a rare meteorite with an estimated value of $100,000. 30-year-old doorstop turns out to be a rare meteorite Skip ...
