Abstract

FROM the isotopic composition of lead in ores, the following empirical formula was obtained1: where CU, CTh and C204 stand for the weight concentration of uranium, thorium and lead-204 in the material of source from which common leads of ores were derived. The purpose of this communication is to treat this formula from the aspect developed in recent investigations2–4 of the geochemistry of lanthanides and to extract some numerical information therefrom.
