(PhysOrg.com) -- For most of modern science, researchers have believed that the Earth was primarily made up of enstatite chondrites, a subclass of meteorites. This was because of the similarity of chromium, nickel and oxygen isotope proportions found on Earth as they compared to enstatite chondrites. Now however, new research by a pair of French geochemists studying silicon isotopes found on Earth, the moon and several types of meteorites, suggest, as they describe in their paper published in Science, that the ingredients that make up the Earth are likely more diverse.
