Metal, iron, & nickel | Some Meteorite Information
Because chondrites are rich in metal and the metal is rich in nickel, all chondrites have bulk (whole-rock) concentrations of nickel of 1.0-1.8% (i.e., 10,000-18,000 ppm). That is 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.
