The most abundant element is O. This is followed by the 3 about similar abundant elements Mg, Si and Fe, which are closely followed by S. About an order of magnitude below are Al, Ca and Ni, which is why CAIs are rare. Only a little less abundant as these are Na, Cr and Mn. All these elements are represented in the abundant silicates, metal, sulphide and the CAI-minerals. The REE are 6 orders of magnitudes below the main elements Mg, Si and Fe, which is why REE element concentrations are given in ppm.
