The main features of the geochemistry of scandium are known through the work of V. M. Goldschmidt and Cl. Peters (1), who also utilized older data especially from the publications of G. Eberhard (2). The principal result of the investigations of Goldschmidt and Peters was that, contrary to earlier views, the amount of Se present in the Earths' crust is concentrated largely in the ferromagnesian minerals of basic rocks, particularly in the augites, which contain on the average about 0.01 % Se.
