Iron chondrite
WebIron meteorites are very dense, 7-8 g/cm3. Most meteorites are ordinary chondrites, and ordinary chondrites have a density half as much as irons. Most ordinary chondrites are in the range 3.0 to 3.7 g/cm3, which is denser than most terrestrial rocks. WebChondrites have low concentrations of CaO. The ratio of CaO to Al2O3 varies greatly in terrestrial rocks. In contrast, in most meteorites, virtually all the Al2O3 and most of the CaO is carried by feldspar, so there is little variation in CaO/Al2O3. Among meteorites, MgO necessarily increases with Fe2O3(T) + MgO.

Chondrites can be differentiated from iron meteorites due to their low iron and nickel content. Other non-metallic meteorites, achondrites, which lack chondrules, were formed more recently. There are currently over 27,000 chondrites in the world's collections. See more A chondrite /ˈkɒndraɪt/ is a stony (non-metallic) meteorite that has not been modified, by either melting or differentiation of the parent body. They are formed when various types of dust and small grains in the early See more Chondrites are divided into about 15 distinct groups (see Meteorites classification) on the basis of their mineralogy, bulk chemical composition, and oxygen isotope … See more Because chondrites accumulated from material that formed very early in the history of the Solar System, and because chondritic asteroids did not melt, they have very primitive compositions. "Primitive," in this sense, means that the abundances of most … See more Chondrites were formed by the accretion of particles of dust and grit present in the primitive Solar System which gave rise to asteroids over 4.54 billion years ago.

The degree to which it … See more These meteorites either contain a proportion of water or minerals that have been altered by water. This suggests that the asteroid from which these meteorites originate must have … See more WebIron oxides Magnetite (Fe2+Fe3+2O4) and hematite (Fe3+2O3) are oxides of iron. Magnetite occurs as a trace to minor mineral in several kinds of meteorites. Rubin (1997a) states that it is the “principal oxide phase in the CK chondrites,” a rare type of meteorite (0.3%).
