Abstract: Rare Earth Elements (REEs) were evaluated in two locations in Garri, and Gam mountains, from Chromite rocks in Blue Nile State, South of Sudan. Chromite-spinels are one of the important REEs host minerals and can be a potential source for the REEs. The main objectives of these studies are to determination REEs and some minerals from chromite rocks in Blue Nile state, South of Sudan. Thirty samples of Chromite rocks were collected from different location in Blue Nile State, twenty samples from Garri mountains area, and ten samples from Gam mountains area. REEs were measured by inductively coupled Plasma Optical Emission Spectroscopy (ICP-OES), and other elements in the rocks were measured by X-ray fluoresces (XRF) spectrometer of Cd-109 source and (Si-Li) detector. Independent t-test was used to compare the average means between two locations. The average values of chromite rocks analysis in this study compares well with data reported by other researchers locally, it revealed a good agreement, however, slight differences exists when compared with global data. The results showed that a Gam mountain was higher in Cr and Fe metals compared than the Garri Mountains. The results indicate the positive correlation coefficient suggests irreversible existence between chromium, ferrous, and calcium, oxides. The amounts of ferrous and calcium oxides in chromite rocks are directly proportional to the content of chromium oxide. They increase with increasing chromium oxide in the sample. Magnesium, aluminum, and silicon oxides are reversibly proportional to chromium oxide contents. They increase with decreasing chromium oxide. As for REEs the data showed that Gam mountains were highly significant (P≤0.01) in both Yb and Er elements concentration than the Garri mountains. The average concentration of( LRRs), Ce, Pr, Nd, Sm, Eu and Gd, were, 12.22, 4.9, 3.4, 0.44, 0.22 and 1.76 ppm, while the (HREEs) Y, Er, Tm and Yb, were 0.35, 1.76, 0.32 and 0.17 ppm, for Gam Mountain respectively. AS for Garri Mountain the averages concentration of (LREEs), La, Ce, Pr, Sm, Eu, and Gd, were 0.03, 0.3, 4.10, 1.90, 0.12 and 1.37 while the (HREEs) Y, Ho, Er, Tm, and Yb, were 0.34, 1.16, 1.22, 0.98, and 0.10 ppm respectively, which Comparable with the chondrite and mantle normalized types the data showed the shape of these patterns is parallel, the elements of Er, Gd, Sm and Nd are above chondrite normalized for Garri and Gam mountains except for Nd is lower in Garri mountain but Y element is lower than the chondrite in both area. As for mantle normalized the results indicated that the elements of Sm, Gd and Er are above of the mantle normalized but the elements of Ce and Y are lower. There for Rare Earth Elements(REEs) found in chromite ore and enriches because the Chrome-spinels are yet little examined with respect to the distribution of lithophile trace elements, REEs included.
