what types of metals are in meteorites
Iron-nickel means that the metal is mostly iron but it contains 4-30% nickel as well as a few tenths of a percent cobalt. Iron-nickel metal in meteorites also has high concentrations (by terrestrial standards) of rare metals like gold, platinum, and iridium.ecause chondrites are rich in metal and the metal is rich in nickel, all chondrites have a bulk (whole rock) concentrations of Ni (nickel) of 1.0-1.8% (i.e., 10000-18000 ppm). That's 100-1000 times greater than practically any terrestrial (Earth) rock. An Earth rock with as much as 1.0-1.8% Ni would be a nickel ore.
