Abstract. Particle Induced X-ray Emission (PIXE) has been applied to a analytical tool for long range of major, minor and trace elemental analysis in Precambrian charnockites. PIXE is sensitive and non-destructive method for some elemental analysis in a variety of Precambrian charnockite rocks down to levels of a few parts per million and it is not valid for all remaining elements in the composition. The elements identified in the Precambrian charnokite rock are Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Ru, Ag, Pb are identified without exact values by PIXE but the elements minor F, major elements Na, Mg, Al, Si, P and Ba and traces of Co, Th and U not detected due to various reasons even though there present in the charnockites, because of PIXE which is operation at 3 MeV energy and characterization material of charnockite mineral investigated. In mineral characterization of charnockite rocks, elemental errors in concentration of the compositions explained by comparing with present and previous studies.
