Description
24 Ultramafic rock samples from 3 different areas of the Schist Belt of Southwestern Nigeria were analyzed for 11 rare earth elements (REE) by instrumental neutron activation analysis (INAA). REE patterns of the ultramafic rocks are similar for the 3 different areas, and the REE abundances are smaller than for other types of rocks from the same areas. However, the moderate fractionation between LREE and HREE observed for these samples is unusual for ultramafic rocks. Some geochemical implications of the results are discussed.
