This paper gives a brief account of the present state of knowledge concerning rare earth element fractionation in terrestrial rocks, reviews present methods of plotting and comparing results, and examines the comparability of data obtained by neutron-activation analysis and X-ray spectrographic techniques. A large number of analyses have been replotted by a new method, and several conclusions conceming differentiation in terrestrial rocks are drawn from the results.
