Meteorites made of nickel-iron and silicate minerals include pallasites, which are made up of olivine crystals scattered in the nickel-iron with the corners of the crystals touching each other, and mesosiderites, which have less nickel-iron than pallasites and have a texture similar to achondrite with nickel-iron dispersed (called howardite).
