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.

Increasingly, attention is being paid to declaring the origin of agricultural and marine products after the advent of the bovine spongiform encephalopathy (BSE; commonly known as mad-cow disease). The display of the production centers onU. pinnatifidahas been required in Japan since 2006. As an example of testing in another marine product, near-infrared spectra (NIR) and trace elemental analysis ofU. pinnatifidaare proven effective methods for discriminating production centers by us and Food and Agricultural Materials Inspection Center (FAMIC). In the present study, we found that X-ray fluorescence analysis of Br was also effective for the discrimination of production centers. The results of our study suggest that a combination of NIR and X-ray fluorescence analysis is a convenient and efficient method for determination due simple sampling procedures and increased effectiveness.
