Abstract

In this study, rare earth element content of Minim-Martap Bauxite Deposit was determined and analyzed statistically. The Minim-Martap Bauxite deposit is located in the Martap subdivision of the Vina Division, in the Adamawa region of Cameroon. From this region, 17 bauxite samples were collected from different locations. Rare earth element content of these samples was analyzed using X-ray florescence analysis (XRF) techniques and also Statistical Package for the Social Sciences (SPSS) software for statistical assessment. Average rare earth element concentrations are La (171.88 ppm), Ce (311.47 ppm), Pr (40,63 ppm), Nd (166,92 ppm), Sm (36,86 ppm), Eu (8.21 ppm), Gd (31.40 ppm), Tb (3,87 ppm), Dy (16,26 ppm), Ho (1.97 ppm), Er (3.75 ppm), Tm (0.39 ppm), Yb (2.21 ppm), Lu (0.25 ppm) and Y (33.29 ppm). La, Ce and Nd account for 78.41% (11054.6 ppm) the total Sigma REEs (14099.21 ppm) present in the analyzed samples from this deposit. According to Factor Analysis, REE demonstrated their strongest correlation in first component, indicating majority of them were in the initial magma that formed the precursor rock.
