Abstract |
|
|
| The investigation describes the results obtained by PIXE analysis-Geochemistry of high grade metamorphic rocks and comparison with the previous chemical analysis and neutron activation analysis results. The performances of PIXE technique through geochemical analysis of metamorphic charnockite rocks at various levels of elements have been discussed. The reasons at advantages and drawbacks of PIXE as 3MeV methodology with Si (Li) detector and matrix composition of metamorphic geological materials are tried to explain. The experimental uncertainties like incident proton energy, production cross sections, X- ray fluorescence, brumstralung, detector efficiency, matrix effects and limit of detection, resolution at light elements, medium elements and REEs are studied with respect to the well-established Chemical analysis and NAA results of charnockites. |
