Abstract
Microbeam proton induced X-ray emission (micro-PIXE) was used to measure elemental composition and distribution profiles in grains and matrices of phosphorite minerals from northwestern Saudi Arabia. Several trace elements including V, Cr, Fe, Ni, Cu, Zn, As, Sr, Y and U were detected, with concentrations ranging from a few ppm to several hundred ppm. Elemental distribution maps for some of the detected trace elements showed a high degree of correlation. These results are discussed in terms of the geochemistry, diagenetic processes and the genesis of the phosphorite ores.
