Description

The rare-earth content in the Seis Lagos Carbonatite Complex, is dealt with. The crude results of semiquantitative spectrographic analyses show that lanthanum, cerium, praseodymium, neodymium, samarium, europium and gadolinium are enriched in samples from drill holes at the major laterite hill of the Seis Lagos Carbonatite ocurrence. Yttryum also shows anomalous content. (Author)
