<p>Proton induced X-ray emission (PIXE) was used in the analyses of geological samples to determine accurate deposits of chromium and other trace elements. Fourteen samples were collected from sites suspected to have chromium deposits, then prepared to the required standard to be interrogated by the above technique. Samples were irradiated at Centre for Energy Research and Development, Ile-Ife, Nigeria. From the Spectra and results generated, it suggests significant deposits of Chromium in some regions of Nigeria. Gold deposit was observed to be significant in some areas. Concentrations of Pb, Si, P, S, K, Ca, Ti, V, Cr and Mn elements were determined as well.</p
