Rock samples from three magmatic complexes of the Lovozerskii massif of the Kola peninsula were examined to determine the zirconium and hafnium content. The results are tabulated and show that the contents range from 0.07 to 2.31% ZrO/ sub 2/ and from 0.015 to 0.057% HfO/sub 2/. The variations in the zirconium/ hafnium ratio are insignificant. Zr and Hf are concentrated in late magmatic complexes with 0.167%, 0.29%, and 1.49% ZrO/sub 2/ in the first, second, and third complexes, respectively. Agpaitic rocks have a higher Zr and Hf content than miascite rocks, but no relationship could be found between sodium-potassium and zirconium-hafnium contents. (TCO)
