Keywords: Rare Earth Element (REE), ICP-MS, Nepheline synite, Igneous rocks.


           Rare Earth Elements(REEs) were evaluated in three locations in sulaimani, Kurdistan region , five types of rock were selected (alkaline, peralkaline, mafic ,iron ore and intermediate rocks).Decomposition of the rock samples carried out  by Lithium MetaBorate  fusion ,the final sample  solutions were prepared in 4% HNO3.ICP-MS technique was selected for analysis of Rare Earth Elements  in the rock sample ,results show presence  of economic level of some Rare Earth Elements  in Qaladza location (Bulfat mountain group),the high grade of Rare Earth Elements  deposited in  Nepheline synite.The best accuracy and precision were obtained by ICP-MS technique, the  D.L for most Rare Earth Elements  are between (0.01-0.3 ppm),with (0.999)of correlation coefficient , the solutions of the blank, standard solutions  are monitored throughout the analysis  and the analysis of duplicate also performed to obtain a good accuracy from our analysis.
