Meteorite classification may indicate that a "genetic" relationship exists between similar meteorite specimens. Similarly classified meteorites may share a common origin, and therefore may come from the same astronomical object (such as a planet, asteroid, or moon) known as a parent body. However, with current scientific knowledge, these types ...
Most meteorites are stony meteorites, classed as chondrites and achondrites. Only about 6% of meteorites are iron meteorites or a blend of rock and metal, the stony-iron meteorites. Modern classification of meteorites is complex. The review paper of Krot et al. (2007) [17] summarizes modern meteorite taxonomy.
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 ...
The Karin family, formed 5.8 million years ago, and the Koronis family, formed 7.6 million years ago, account for a class of meteorites called H chondrites that represent 33% of known Earth ...
Spectral class – Stony meteorite – a meteorite composed mostly of silicates. Stony-iron meteorite – a meteorite that is a mixture of meteoric iron and silicates. Strewn field – a field of fragments from one meteorite fall. Structural class – a subdivision of iron meteorites in ataxites, hexahedrites and octahedrites.
Carbonaceous chondrites or C chondrites are a class of chondritic meteorites comprising at least 8 known groups and many ungrouped meteorites. They include some of the most primitive known meteorites. The C chondrites represent only a small proportion (4.6%) [1] of meteorite falls.
Ochansk Meteorite, an ordinary chondrite with a fusion crust, found in 1887 in Russia. The ordinary chondrites (sometimes called the O chondrites) are a class of stony chondritic meteorites. They are by far the most numerous group, comprising 87% of all finds. [1] Hence, they have been dubbed "ordinary".
The meteorite offers a look at a rare carbonaceous chondrite, a high silicate rock containing approximately 2 percent carbon by weight. It is the first of its type to be discovered in the United ...
